Simpsons Rule - Approximate Integration.
In this video, I give the formula for Simpson's Rule, and use it to approximate a definite integral.

it's been 12 years, yet you still invariably support me through my calculus class. come on bois let's show our appreciation for this man
When my math teachers give us those damn surveys on how to improve I just give them your site.
Mid NuLL ha, thanks!
I just took a break to say thank you! this video is over 7 years old and its still uiseful. God bless your kind heart for sharing
Math doesn't age, so of course it's still useful :)
No hell yess
11 years and still helping*
Man is getting me through my calculus class
You and IntegralCalc are alot of help, college profs are not worth listening to anymore with these amazing videos
Helped A LOT. Thanks as always for explaining things so clearly. You could definitely teach a lot of professors so much about clarity.
@RickRubik you would use partial fractions on this one.
however, not every function can be integrated using elementary antiderivatives, which is one reason why we need approximation techniques like this.
@NappySupreme well, we are approximating the value of that integral in a round about way (which is why there is no actual integration)
you just save my ass from tomorrow's exam :D
by the way , there was a Simpsons problem in the exam , and i got the highest score in my class :D
thanks man :D
Ahmed Ali You are both an inspiration!!
SAAAMEEE
sAMMMMME
SAMEEEE
Thank you! Had my first class on this today and it went right over my head. You helped me out a lot
These video are just the best, so clear and helpful and makes understand things so much quicker. Thanks!
I have a Computational Physics exam in few hours from now, and this just helped me immensely. Thank you!
After being thought left/right/midpoint/trapezoidal rule all in one day, I lost focus before Simpsons Rule, so my notes were incomplete. I will have to ask my teacher whether we are expected to know the formula for this, as she gave us a calculator program to do it, but it feels nice to complete my notes regardless.
Thanks man!
patrickjmt you are awesome. I cant believe it takes math professor such a long time to teach something this simple.
You're pretty good at explaining calculus. I get the concepts much faster after i watch your videos than when I sit in class.
For some reason, your explanations always make things understandable.
Wow. This is beyond fabulous. It's amazing how many fabulous videos you can find on CZcams explaining math. I can sit in class for a full hour listening to the teacher talk about it and see her do fifteen different examples and not have a goddamned clue. But I go home, look at the homework problem, see what it asks, and type into CZcams "How to approximate area under curve via Simpson's Rule." I don't even have to get a quarter of the way through the video before it makes perfect sense.
@AgariRG well, antiderivatives have tons and tons of applications. not all functions have antiderivatives so some method of approximating them are needed; this is one of those techniques
Time to understand and how to do content:
By my teacher: 2 - 2 1/2 hours
By patrickJMT: 7-10 minutes
Ty, studying for my Calculus 2 final. I am now 100% crystal clear on what Simpson's rule is thanks to your super clear work. Thanks very much.
I'm doing a Civil Engineering Diploma and for the past 2 years Ive got to know Patric's left hand pretty well! Thanks for the videos Patric!Writing my last Math exam tomorrow and I feel like Im gonna ace it! Thanks to you and Sal!
man youre the best math guru I know around here, thanks for your help
Patrick thank you so much for doing these videos. You are a math savior!
@Shanongao no worries ;) i would like to start doing proofs/justifications of the theorems. it seems more people would like to see those than what i originally thought. i always just assume 99% of people skip over them (which probably is true)
My teacher made this seem so intimidating. But you're right, it's a lot of tedious arithmetic.
Thank you for everything :) I've lived off your videos for the past 5 months, and will continue to do so at least for another week until my final exam! Then there's Calc II next semester...joy unbound.
Thanks again!!
Beofre seeing this video, I just saw a youtube ad for "Study Pug". It said "Still searching for youtube videos for math help? Are those math videos from 2006 really helping? Try Study Pug!"
Well, Study Pug, I can say with certainty that Patrick JMT's video are old, but they certainly are helping me astonishingly well.
Missed this lesson in class but glad I stumbled across this video, very helpful video massive thanks!
Simple and easy trick explained by you really superb .
@ITSxUNKNOWNx you are very welcome!
Wow this was so helpful! :D I was staring at a problem like this for almost an hour and I couldn't figure it out, but you've helped so much :D Thanks! :D
Thank u so much 😮 it's been 15 years since u upload this content it help me alot 😢
@annedesiree02 glad you like them. you may also check out the calculus playlists although not everything is included in there!
Well i'm glad to see someone work this out. Stewart 7th edition doesn't explicity state that the points you use while computing the function values are the right end points (which in this video that is what you used.) Not sure why that is, but thank you!
Your hand writing is very beautiful and your explanation is very clear so basically you're perfect. Thank you.
I LOVE YOU PATRICK! I FINALLY LEARNED THIS WITH YOUR HELP!
you helped me through my A-levels, now still helping me on my masters. you legend
Your videos are awesome. They help me immensely in my calculus class. Thanks!
you've really helped me a lot ..i still wanted to listen from you about the errors in trapezoidal rule
Excellent description, thanks a lot sir.
You just broke down the whole thing in 7 minutes. Genius!!!!
I honestly love your video it really does help a lot thank you so much
Thanks so much. I'm doing independent calculus and I was so lost, but this really helped. Keep it up!
your work is always great
tnx sir
This was an excellent example made be understand the formula from my book..Thank you Patrick
Thanks for sharing a nice collection of your videos. Easy to follow and well-explained ^_^ Just subscribed. Please keep it up.
Good video,very clear,and it really helped me
THANK YOU!! FOR ALL YOUR VIDEOS!
I'm writing and AP calc exam and this came up in the review, thank you man!
@Shanongao no, i do not derive the formula. the derivation / proof is in any calculus textbook.
@MrJigab00 well, most people watching calculus videos have a calculus book, so the proof/justification of the formula would be in the book. i am sure you could also just google something like : proof simpson's rule calculus, and you could easily find something on the net about it.
The fear of him smearing ink kept me on the edge of my seat the whole vid.
Thanks for making this video. Very clear and helpful. Cheers!
Thank you so so much. This has helped me a great deal!
Neatest board hand writing for calculus I've seen. Cheers for the great video
Thank you very much for this video. Because of you I figured that I just have to focus because it seems easy
Your videos always help me.. superb job..
Your videos is such a great help :) thanks a lot . I''m actually using those as a guide to understand our lessons :)
Thank you very much, I was exploring all corners of the internet to find what x sub 0 was for simpson's rule, and you just labeled it :).
thank you very much for making these videos they really help. I'm studying for my calculus test and the video really helped.
10 years later and this works...Thanks a lot
Wow, you did a better job explaining this than most college professors! Nice vid :)
patrick u are a life saver thanks a lot
Thanks for the help!! Easy to understand!! Nice work
thank God you're always there to help me
Much love for the videos. My Calc book doesn't have any good examples. This helped a ton!
Thx a lot Patrick like always
You are awesome, thanks so much for doing this for people who need extra help!!!
Thanks for the vids keep em coming.
This was super helpful. Thanks!
I could learn calculus without going to school just by watching your videos!
awesome work man and thanks :)
Thank you so much!! You made that so simple!
Extremely useful, as always.
thanks! you made me remember what my tutor taught me :D what you can do is to take 4 common for the odd numbers, and 2 common for the even numbers :) it really saves time!
Thanks for all your videos...I have one question...what is integration used for? Like I know how to use it but what does it do? Like if we try to find the tangent line we take the derivative etc...what does this do?
Man, in Portugal you take this during the 12th grade (last year of highschool). Possibly 1st year of college in Mathmatic Analysis I . On the second year you´re already cacting up with the Fourier series, Fourier integration or complex integration on Mathmatic Analysis III . But I really liked the explanation... simple and accurate. And I stumble upon this looking for the Simpson series from Fox! :P Thx
I have not been understanding both Trapezoid and Simpsons Rule. BAM!!!!! You are awesome! I totally understand now and have been misunderstanding the process. Where can I find info on Role's Theorem and mid point theorem?
Great video! Thank you sir.
Hello patrickJMT,
Thanks alot for your educational videos. This really helps some people alot!
Keep on going :-)
Nice video regarding the calculations behind Simpson's Rule. One criticism I might have is that (assuming you did not do it in a previous video) you never showed what Simpson's Rule is (that is, SIMP(n)=1/3(2*MID(n) + TRAP (n)). This of course leads to the general plug-and-chug equation you had above. It would probably help a lot of people out if you had derived the above series from Simpson's rule, which is just a weighted average between the midpoint rule and the trapezoid rule. I know this is nearly 6 years late, but I figured i'd leave some constructive criticism here anyway. Again, nice video.
@HadiJ89 it is just a way to approximate an integral. you can use it whenever you want. most problems you would see on a test would ask you to use it. typically n will also be specified.
Thank you!! Very easy to understand!
Drinking game: take a shot everytime he says "very tedious"
+Ratkovski Adajet or "um"
or "okay" at the beginning of each video haha. love you +PatrickJMT
@SonOfNye yep, i have noticed that too : )
Thank you so much. Clear and practical!
Thank you for helping me get this! Need to ace this test! Calc two, tough stuff!
really help me understand the basic, Thank You sir ^_^
and do you have tutorial for romberg solutiom ?
Great video thanks. Helped me a lot
Thank you very much! I just had one on the test this week. {Question 6) Approximate ln(3) = intergate from 1 to 3 (1/x ) dx Using Simpson's Rule. Use n = 4. A) 1.098 B) 1.099 C)1.100 D) 1.101 E) 1.102 F) 1.103
we love you patrick
Quick tip, if you have a TI-84 (or whatever) you can make life MUCH easier by storing the function in y1 [hit y= and enter the function in] then when you go to do the computation, hit vars --> Y-VARS [enter] then select the y whatever you stored it in. Your calculator will display Y1. Now just throw some () on that, so Y1(0) and it will evaluate the function stored in Y1 at the given point.
so all together this function would look like (1/2)[Y1(1)+ 4Y1(1/2) + 2Y1(1) + 4Y1(3/2) + 2Y1(2) + 4Y1(5/2) + Y1(3)]. should save you a lot of time.

Really helpful for my exams coming up. Thanks alot.
this helped me so much! i love u dude.....
Very neat and easy to go by , cheers!
Very Helpful! Thank you.
Thank you! This really helped me :)
THANK YOU SO MUCH. I WAS HAVING TROUBLE UNDERSTANDING THIS AND IT WAS ANNOYING ME, BUT SINCE I WATCHED THIS I UNDERSTAND IT ENOUGH TO FINISH MY ASSIGNMENT. CAPITAL LETTERS!!!!
You, sir, are a rock star.
1 minute of your video made me understood more than 30 minutes on the web.
Thanks.
you are most welcome!
There are many applications for such formulas. For example, since computers do not calculate over a continuous period, they must make many small calculations at discrete points, and cannot easily "guess" at integrals as we do. In the case of most mathematics software, they use methods such as this with a very high "n" to compute the answer they give you.
Sir, the approximate value of the integral calculated using Simpson's rule (1.074915) is in close proximity to the exact value which is 1.065878. This itself shows that the Simpson's rule gives us better results in comparison to the Trapezoid rule as we approximate the function with a quadratic polynomial in case of the former while with the help of a straight line in case of the latter.
How did you compute that in your head.... it took me like 2 minutes to double check on the calculator alone..... you sir, are a god!
