Please buy my book!: '1001 Calculus Problems for Dummies' - you can get it on my website: patrickjmt.com/
Trigonometric Substitution - Example 1. Just a basic trigonometric substitution problem (still long though!). I show the basic substitutions along with how to use the right triangle to get back to the original variable.
I just love how the majority of the examples you do, you do them in permanent marker.....no mistakes, such a beast.

May be sir just redo everything when he got a slight mistake.
I know im asking the wrong place but does anybody know a tool to log back into an Instagram account?
I somehow lost my password. I love any assistance you can offer me
@Jaime Boston Instablaster =)
@Jimmy Randy Thanks so much for your reply. I got to the site through google and im waiting for the hacking stuff atm.
Takes quite some time so I will get back to you later with my results.
@Jimmy Randy it did the trick and I now got access to my account again. I'm so happy:D
Thank you so much, you saved my account!
I have learned more about integration from patrickJMT than from my math book, seriously.
That moment when patrick JMT drops a sick beat while doing calculus. (12:09)
This made me laugh a little more than it should have.
This is the most funny thing I heard today, youre awesome
hahahahaha
hahhaha DJ JMT!
4 Years later, I'm still laughing at this. I love the internet!
Pat I would venture to say that you have single-handedly affected more future scientists and engineers than any other man in the world with these videos. thanx
I can't imagine how many all-nighters I pulled just to watch his videos and understand everything so clearly. It makes calculus so easy cuz of him. :D By the way it's 2:59am RN and still seating on my chair listening to this guy. Thanks for saving my grades!
I cannot express in words how much I love you for this right now.
RE S I was filled with despair but this video showed me true hope
@hunterwilbanks donation link on my website ; ) feel free to send as much as you like!
I realize you may not see this comment since the video is so old, but during the summer I took Calculus 1 online and didn't buy the book, because I knew I'd have your videos. This content should not be free and yet it is. It helped me get an A in Calculus 1 and now this semester I am in Calculus 2, I yet again didn't buy the book and am relying on your insightful videos. You help immensely and are the secret to my math success in college. Thank you Patrick.
glad i could help!
and why shouldn't this content be free? :)
How many people made this far(Calculus II)? We are absolutely minority.
+SMEXY! Nah, man. You're in a minority once you finish diff eqs. and linear algebra.
+Victoria Havlicek Abstract Algebra
Marcus Hines My point is that you're in a minority once you finish courses that emphasize computation.
+SMEXY! i took calc 1, calc 2, calc 3 and diff eq, then transfered to a diff school, but couldnt get calc 2 to transfer (grade below a c), so im taking it again..one would think its not as hard...but nope..here i am watching these videos...again, and thank you +patrickJMT
I did up to Linear Algebra and ODE
You are the only person in my life who explains math in an organized, straightforward, easy to understand way. THANK YOU. My math professor writes on 6 boards maybe 10 times during class and I just give up, but you sir, thank you
@zloyhimik typically people do not want to see it this way; using the right triangle produces a much more simple equation
Just wanted to say thank you for doing the Lord's work
+Rob Miles jesus, math teacher extraordinaire
+Rob Miles thanks for the laugh
I will pass calculus 2 because of you. You're the hero this world needs. Keep doing amazing work
"I'm not lazy; I'm efficient" haha
Wow, i actually get it now. My professor skipped like 10 million steps during lecture
They have a habit of doing that
Yea. So did mine
did u graduate yet
@@whatshouldwecallyou9503 probably
Lol they do that too often
"Hallelluyah we have our solution lol"
*Hallelujah. A fair misspelling considering it is not a common word.
It's 1:01 AM right now and I got what I needed from you for my midterm in a 9 hours. Subscribed since 2013 and still going, thanks Patrick.
Me : hey sis, have you seen a pencil? I'm about to study math.
Sister : There's a pen right there....why don't you use the pen?
Me : I'm no patrickJMT, I'm not at that level...
@JohnSmith3870 glad to help! and what do you mean: if they ever get taken down with the whole censorship thing...? they are my videos, i keep them here with the help of youtube/google. :)
lol got an ad before that said "are you sick of youtube video from 2006"...why no, no im not. these video's are timeless and absolutely perfect. thanks for helping everyone pass calc 2 for free, keep on keeping on.
how do u hear video? mine wont play audio? :x
@geekgal1000 ya, not everything is on the website ( but most of it should be!)
Once again you've explained something clearly in 14 minutes that a professor couldn't explain in an hour and half of lectures. Not only do you do it in a way that's understandable, you show WHY I'm doing this, my book and professor just assumed I knew that I was factoring the 'a' out. My book doesn't even have the triangle trick. YOU ARE GOD!
God Bless You, I was literally about to cry in the class when my professor was explaining this.
It never fails me how amazing it is how much easier it is to understand this stuff when this guy teaches it. You truly have a gift. It may as well be a foreign language when my profs teach this!
Man I got a Calc 2 exam tomorrow and I think you might have just saved my life!!!
did he save your life
Are you still alive? I got a calc 2 midterm tomorrow aswell
No response. Guess he didn't make it...
Joe Billy they tend to throw curve balls on exams. He should have taken this basic explanation video and applied it to more challenging problems before his exam!
@Puggalug yep, this is true!
@vanadinite01 no problem, happy to help : )
@sunnysideup no problem, happy to help :)
@cgsuperpanda1 no problem, happy to help : )
i hope the final went well!
@pabloMTv ha, nice to see i am missed. i was actually spending some time getting things organized (playlists and stuff) and also working on trying to get some iphone apps out (almost there!). so, i have been doing stuff, just not creating new videos, which is unfortunate, as i hate organizing and like making videos. c'est la vie though, it is stuff that needs to get done!
hope you are doing well!!
there is a ton of stuff missing from my website. it is a nightmare to keep updated
@powercrazy11 glad it helped!
I ve watched his video as soon as I `ve had too much trouble with Math. He helped me a lot and he `s better than my teachers ever! Thank you for sharing this awesome video!
@angelsword1000 you are very welcome
You never fail to help me understand even the most complex problems. You are an excellent teacher. Thank yiu so much for these amazing down to earth and free explanations
You're the man. You should have seen the looks on my calc classes' faces when my teacher (who speaks little english) introduced this topic after we were still reeling from trig integrals. Priceless lol, but as always I come to your videos and understand everything. Truly thanks.
I love you Patrick. I'm sure you saw this post on another one of your videos, but again I say thank you. You are the reason I graduated man.
Even though I have a great calculus teacher I love going to you for your videos. They help solidify the concepts and sometimes help me wrap my head around some concepts. Thank you.
You have outdone 2 weeks of my professor's lectures in 14 minutes and 8 seconds.Thank you for being you
glad i could help you out
Love the way you go over examples and show every step. Don't even know why i go to class when my teacher doesn't know how to explain!
You're such a good teacher that your videos don't even require sound and I understand them
Patrick I can't even tell you what a help your videos have been to me. My Calc 2 final is tomorrow, and I'm going back over my practice test, when I come across this trig sub question, but I've totally forgotten how to know which one to use... Then I just look up your trusty videos, and you saved the day again! You're a saint.
@42marthacu glad you like them : )
This channel is a blessing from beyond. My math prof comes nowhere close in comparison to your clarity.
So far this semester, I haven't attended a single lecture for my Calc II class. I watched like 10 of your videos the night before my midterm and I aced it. You are my hero...
I'm a student from Malaysia and your videos had been extremely helpful . Thank you so much !
Your videos are very helpful. Thanks for all the hard work and for making these videos free.
you sir, are a saint because I cannot understand one thing my professor is doing, and you made it 200x easier! thank you
Such a good channel. You explained everything perfectly, no skipping steps but still so concise. Thank you.
glad i could help :)
You go faster than the other videos but not too fast, so at my level, your speed is perfect and thanks for the free math help i am getting of you. Be blessed.
i watch your videos for quick refreshers every time I have to tutor someone. I appreciate your videos greatly
Wow, I actually understood this, khanacademy and my textbook kept confusing me
come here first. my videos are better.
patrickJMT we know :)
this guy is amazing :v
For real those Khan videos suck lol
If khan Academy confuses you, then you probably have a below average IQ. How do u not understand that man? smh
My Calc 2 teacher only confuses me more. I really appreciate all the examples. It helps so much with my homework and makes me like math! You should be a college professor if you are not already since you seem to have a gift in explaining complex things.
6 years later and still the best tutorials i've seen!
This is more then helpful! I am now able to understand the entire concept of these kind of problems... I was so lost in class and you just made it clear... I understand it so perfectly now. Thank you so much! I wish you had an Idea of how much help this is to me!
You're so much neater and more organized than the instructor at the math review I went to today!
I love you, I seriously watch all your videos
THANK YOUUUUUUUUUUUUUU!!!!!!! This video was so helpful! Best help I've received thus far from all your videos. They were helpful as well but this was HELPFUL!
Thank you so much for posting this! I just learned more in 15 minuted from your video than I have in 2 hours of my calc class!!!!!!
You are a lifesaver. Keep up the good work.
Great video and clear instructions! Thank you!
You sir are a king.
Thanks for taking the time to post these.
Really Patrick, you are a blessing, I'm a 65 year old composer who decided to learn calculus; I followed the full 18.01 at MIT and got lost: But with you it is pure poetry a beatiful game and your pedagogy is EXCELLENT, I know I am an emiritus teacher at university of Montreal (music). Thans a thousand times. Michel
you are the life saver bro just up keep the good work,you are appreciated a lot.
WOW that this video was so helpful. I missed lecture for this topic and after watching the video don't feel behind at all! You ROCK! :)
these videos r really helpful. awesome content!
Thank you Patric, I learnt a lot from your videos (especially calculus)
Once again Patrick delivers.
thanks for making this topic easy to understand, keep it up Patrick.
Wow. How convenient. I was just getting ready for a trig sub lab, and this video helped me out big time. You are basically my calc professor
Thank you so much! I really love your detailed solutions! Helping me to get through first year Calculus :)
thanks PatrickJMT! Your tutorials are much easier to digest than the material in James Stewart's Calculus Early Transcendentals!
patrickJMT PATRICKKKK once again saving me !! ilyyyy brooooooooooooo
"we are going to use a trig identity thats going to make everything go away"...... you gave me peace when you said that
What I meant is, the steps just going through the problem is a lot. Thanks for your tutorial.
YOU ARE A GENIUS.
Nice Job, Really helped me out with my classwork, and found some new methods of substitution Thankx!
I could never understand my Calc BC class without your help, thank you soo much!
You're videos are so helpful!!!! thank you so much!
Thank you so much for posting this, all your hard work is much appreciated!
Splendidly well explained!!!
Saved my life again!
Thank You So much for doing these videos.
This guy is my favorite math tutor lol. Well done, great video.
Work for that youtube money! These videos are a haven for me for exams, thanks man!
started learning this topic this week, goes on this channel to watch a ton of examples and understand, you are the cod(call of duty) god of calc!
So I'm from South Africa and I'm also doing calculus. Since watching your videos after my first test till now, my marks have improved by almost 40%. I am writing a test again this week so I just bought your book (yikes to the Rand/Dollar ratio), but thank you for the great videos and all the help!
Very clearly done. Thanks Patrick.
thanks a lot man! i really needed to know how to do this and you helped a lot!
The video I needed. Thanks, very clear
Needed this to refresh my memory. Taking differential equations next semester and need to re learn integration techniques.
Thank you! for some reason I could not wrap my head around this. but you cleared it up!
I love your video! It really help me a lot!
Thank you very much ..... U just saved me from screwing up in exams ..... And now I m 100% confident that I can skip my calculus classes and Patrick will save me XD
i never understood the right triangle part until your video,thank you!
You are a blessing to humanity
thank you sooooooo much!!!! i had nooo idea how to figure out where the units go on the triangle... my professor always did it as one of the first steps and i was like huh? but doing it later in the problem like you did is sooo much easier to understand! thanks bunches
Thanks for video and explaning everything part by part
I have a quiz tomorrow on this hoping it will help.... I watch your other videos and UR DEF THE BEST TEACHER/WEBSITE ONLINE!! Id say better than KHAN ACADEMY! :D Thanks for putting this up you're seriously the best!
man great timing. i just learned this lesson today. love you man
