This channel will contain video math lessons for some of the courses that I teach. Currently there are all the Trigonometry videos posted. I am currently beginning to work on AP Calculus AB videos. And, hopefully coming soon will be the videos for my College Algebra course.
On occasion, you may also find videos pertaining to my cross country and track teams as well.

Thank you for this, it helps me a lot to understand clearly the process. Big 👍
Why aren't your video views increasing? And not reaching people? The reason is: 1. Your video is not being SEO properly 2. Your video is not reaching the right people 3. Not using video hash tags properly 4. Not sharing the video on social media There are a few more reasons. That's why your videos are limited to your channel. Can't get out In a word, your video is awesome. Such videos are in great demand. If you do these things correctly. Hopefully, you will get a lot of visitors. Feel free to ask me any questions.
Very helpful you deserve 100m subscribers😢
while doing fractions, why did you use the ''denominator'' 20 and not another number?
thank you good sir
omg you saved me thank you so much jim i love you
Can anyone expalin how he got negative 7x on the 3rd step of the 2nd equation?
Can we represent diameter as DAF
You're a a real one dude. Thank you.
👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
thx i really appreciate it
I'm so weird... that pen fidgeting at the beginning makes my skin crawl. 😅
*Promo SM* 😔

Good point. This is a Speed solution. I went through all 60 x 1mn this morning. It was so fun.
Maybe a better way to teach this would be to graph this with an XY grid. Show, (2,1) then explain it's the midpoint of a line. Show point C and infer the other half of line. These are wonderful videos
If I’m “teaching” it, yes I’d agree. If I’m doing the problem for speed (which I am on a timed test) this is my approach.
Excellent videos. You never circle D in this one, but you do say it. My lord, I wish I had you as a teacher prior to taking the SAT
Sorry to ask which topic is this?
i think its complex numbers
Who does matrices in a calculator??
Americans apparently. Pretty sure we weren't even allowed calculators for the linear algebra exam
I effortlessly use the APA format but have no idea what this high school test is asking. What's a "matrices"? 🤣
Lots of people including me for A level Math. it’s saves lots of time. suppose you’re given A & B all 3x3 to show that (AB)^-1 = A^-1B^-1. I’m not gonna try to act genius 😂 at the end of the day all we need is to pass just show the process and punch those numbers in😂 no messing around.
@@wakeful3282 oh yeah I forgot ap math was the beginner level. Since we don't use terms like that here it all gets a bit confusing. Here linear algebra is a course all engineers, physisists and mathematicians have to take. It would be after you finish your first course in mathematics on a university level (Mathematical analysis of one variable) and calculators were not allowed during those exams. Calculators are usually only allowed when the important part of the exam isn't being able to do math, it's being able to understand the equations and which situation they might be used in. Like thermal-fluid sciences.
@@Lt_Lobster you a Mechanical Engineer? 🤣🤣 me too
as someone not from the U.S.... are you telling me your math tests are multiple choice? tf?
Not all tests are, but the ACT is.
IT IS CHRISTMAS BREAK. I DO NOT WANT TO LEARN ABOUT MATH DURING CHRISTMAS BREAK. I HOPE YOU HAD A GOOD CHRISTMAS.
Wrong
3/4 = .75 < 5/6 = .83
It’s -5/6, not 5/6… negative sign is small and hard to see but it’s there.

this is like 4th grade math though. Isn't it?
Calculator? For zeroes? Lame
I came to say the same thing lol. If you're already writing the problem out (which i recommend anyways) you're going to spend more time typing in the math on a calculator than if you just worked it out in your head.
This is the easiest question ever dfuk ☠️
Wait... is this current day math? I solved it forwards and backwards and got 90...
That’s z-score
❤❤❤
Oh my God, it's Albert Einstein
first but where is everybody?
Looking for who asked
Bruh go to sleep
You know math is boring when you spin your pen ahah

Thank you so much for all of the ACT math practice test videos! They truly help a lot!! I was curious if you had any reviewing the Geometric Mean Leg/Altitude theorem? Thank you so much!
Ngl I was lost because I don't think in improper fractions. I was looking for x = 6.5
I've always hated "cancelling" terms, it can lead to a lot of confusion about the underlying operations
I was thinking that 3% and 10^4 were both basically condensed numbers and of means multiply so the problem would look like 0.03 x 4.14 x 10000. Every zero after a 1 when multiplying moves the decimal for the other number once to the right and since decimal point doesn't change what the actual number is then do that first. Each of the other numbers have two places after the decimal each so distribute the decimal movements and the problem will look like 3 x 414. Quick glance and A is the right answer. Probably not the normal way to do it, but I enjoyed pulling out my math tricks for a minute.
That's what I was doing. 😅
Fast way to calculate this without a calculator if it’s unavailable is see that 3% is close to 5% so divide 4.14*10^4 by 20(.05=1/20) which is 2 lots of ten a power of 10 divided by a multiplication of ten cancels out reducing the power to 10^3 then divide 4.14 by 2 getting 2.07 then 3% is 3/5 of 5% so you multiply 2.07 by 3/5 getting 1.242 and lastly apply the power of ten getting 1242 though just doing the approximation of 5% reduces your choices to a 50/50 if time is limited
HA im so not getting that scholarship lmao
Bro straight up said use ur calc lol
Coool
Isn't the intended/quick solution to realize these are 5-12-13 and 6-8-10 (3-4-5) triangles?
I got this right by doing it in my head
not sure if its recommended but SOH-CAH-TOA has still worked for me
I would’ve guessed right 💀💀💀
It’s crazy that at some point, I knew how to do this by heart😅
This is my 6th grade math
