you know you're a good teacher when after only 25 minutes of teaching, the student can identify the mistakes as you go (multiplying by the negative 3 instead of the positive and writing the bracket instead of the sigma) because you taught them effectively over the past 24 minutes. you are the best, thank you!!!
You're right Impuhlz that's how I test my students to see if they are really paying attention...lol Good job and thanks for watching, learning and subbing...and please keep spreading the word and help us reach that goal of 100,000 subscribers by 2015...BAM!!!
Mr. Tarrou! I've been a fan since I found your videos on trigonometry last summer. I just crushed my integrations test yesterday and I want to thank you for your videos that've helped me better understand what my professor, classmates, and tutors are trying to explain. Integrations have been a real head scratcher for me for some reason. Anyway, I've been singing your praises to all that will listen. Keep up the good work! BAM!
HollowPoint503 thanks for taking the time to share your appreciation and successes with us and for "singing your praises to all that will listen"!!! I hope while you're singing you're reminding them all to like, sub, support the ads, share thru social media and with others to keep these free educational channels growing and free:D Students like you make all this work worth it...BAM!!!
Wish you were my professor, always watch your videos to review topics that I don't grasp in class, and I always understand in the the end after watching your videos!! Thank you!
Jannelle Singh you're welcome and THANKS for choosing my channel to watch, learn, like and sub to! Please spread the word to all your friends to watch and do the same to help us keep growing:D
you are truly one of the best instructors I have ever seen. you made such a difficult concept so easy. honestly, could not have pulled off a 3.6 in Calculus 1 last quarter without your clear instruction. I like to express my great gratitude to what you have done. thanks. happy new year.
You're welcome legendwaitforit dary and THANK YOU for taking the time to "thank the teacher" and to take the time to study and find the additional help you needed to supplement your classroom time in order to make that 3.6 happen...BAM!!! Great job on your part as well:) Happy New Year to you as well and I hope you will keep spreading the word for me:D
I enjoyed this way too much, even comprehended it. Got worried I'd end up all duh/dx but you explained it well enough to keep that from happening. Thanks for these. TH-cam videos that actually make your IQ go up (there's a sentence you don't hear everyday.)
Once again, helping me before a big calculus test. Hoping this time around I'm going to pass, because I've remembered to watch your videos. (I even had a classmate ask me about your site. Bam!) I also loved the AP Project video you posted in your playlist. Even if they said derive instead of differentiate. It was greatness. I shared it on my wall. So glad you keep posting awesome videos.
THANKS for the support Lina M ! Sounds like I need to get one of my classes or a bunch of TH-cam students to make a Prof Rob Bob video to spread the word and help get that "M" next to my subscriber count when it goes viral...lol:) I'll keep posting...you keep watching and spreading the word about my channel...and please remind them to Like me on Facebook, Like, Share and SUBSCRIBE to my channel and spread the word to all their friends too...BAM!!!
You're welcome...don't forget to sub and share me thru all social medias and with all your fellow students, teachers and friends who are learning from home now...BAM!!!
Go pass that Calc final like BAM!!! Soho Yankee Glad I could help and it's good to see you are still watching and learning! (funny...that's about how many days I have left before xmas break, wooo whooo:)
This was really great. I had lot of trouble understanding at first, then I watched your videos and did some problems out the Morris Kline book. Understood it in about a hour and it became second nature.
JohnLouisCrutchfield thanks for choosing #ProfRobBob to learn from and sub to and I'm so happy to hear that the lesson was so helpful! ...and at this point I will close with a BAM!!! and hope that you keep sharing that story and my channel with others:)
Charles Amofordjuoh not anytime soon:( I'm currently working on my Calc 2 playlist but teaching full time does not leave me with as much time as I need to add videos as fast as I'd like to. Thanks for watching and subbing and your interest...please keep sharing my channel when the opportunity arises:D
What a nice thing to say and You're welcome SheldonFX ! Thanks for taking the time to study with #ProfRobBob and don't worry about that beer just make me proud and keep "doing your homework" so you can get those A's and when you do hit the big time, make sure students are still watching #ProfRobBob ...BAM!!!
I like the last problem. Sin and Cos are really that complementary to the point where you can get two different answers.. crazy. It reminded me of that double angle formula but instead of 2x it's 4x. That explains the 1/8.
ProfRobBob At time 24min - when you set up the U where did the 4 go in the 4+1/t = 4+t^-1? In your du= -1t^-2 shouldn't that have been du=(4+(-1)) t^-2 to = 3/t^2
I'm making them just as fast as I can:) If I get big enough I could retire from my full time teaching job and just make videos....so BAM!...go spread the word:D
There was a problem I came across that was cos^3xsinx dx where u =cos^3x(get that) but when du=-sinxdx becomes---> -du=sinx ? What exactly are we trying to do with du and dx as far as form? Why take just the negative 1 or divide by 2 like we did in your first 2 examples here?
I thought I posted twice and deleted one of my replies and deleted both, so lets try this again. If you let u = cosx then du = -sinx dx and -du = sinx dx, so you can right original problem -Su^3 du
My book (which is pretty good) uses another way of explaining this by designating a function g(t), and x is substituted for that, the inverse is what lets us go back to x in the end. But it never described why this works in very much detail, a small proof is given. I think this description with differentials is much more intuitive. I am in Europe, so the convention is not u but t for some reason :)
Well i finished another math class again thanks to you Mr Tarrou! Next it's on to calculus 2 and then calculus 3! I was wondering what do we learn in calculus 2 exactly? I've heard it's mostly hardcore trig and you use some of the identities but what do we learn to do in it? Thanks for all your help!
CONGRATULATIONS!!! I'm not really sure about that curriculum, it's been over 20 years since I was in a college calc class...my videos only go about 1/3 of the way thru Calc2, so sadly our journey sounds like it will soon be coming to a close:( But please keep in touch and let us know when you get that hard earned diploma!
THE GOOD O'L DAYS. NOW IT'S COVID & I'M WATCHING THIS VIDEO TO MAKE MY CHANNEL IN 1ST JANUARY 2025. YOU ALREADY KNOW THAT I AM 9 YEARS OLD. I WISH YOU 200000 SUBSCRIBERS.
Hey Shane…I'm using U substitutions to show how to make the problem match the integration rules that you are learning. Not sure I completely understand your question:( Are you thinking about what you learned when doing the chain rule? My book teaches u substitution as a suggestion for those types of problems too.
Well THANK YOU Jim Crews for that testimonial and for choosing Tarrou's Chalk Talk to learn from, subscribe to and share with so many others! If all my subscribers did that I would have a million subscribers too:)...SOMEDAY I will !!!
Throwing this guy some $$$ because I'm angry that I pay a lot of tuition for less helpful material. At least now I'm paying something for both, I'm just getting a ridiculously better deal here.
Just got your paypal "Tip the Teacher" message and sent a reply Tikonu23 ! Thanks for sharing your appreciation in a comment for all of Google+ to see as well...and remember, you can continue to help my channel groW by telling everyone to Like, SUBSCRIBE, Share, support the ads, Like me on Facebook, Twitter, then tell other students to do the same and share this great resource with their friends and teachers too..."together" we can make my woe's dream a reality and get those 100,000 subscribers by the end of the year...BAM!!!
I wish I had classrooms full of self-motivated students like you:) Hope to hear that you pass that exam like BAM!!! Thanks for taking the time to study with Tarrou's Chalk Talk and all the likes are always appreciated! Please keep sharing my channel when you can:D
The problem im doing is 2x (-x+1)^(1/5), my teacher gave us the answer key to check our work and I got one part of the answer, 5/3 (-x+1)^(6/5) but I can't get the other part. Help :)?
Sorry I never got to your question. Were you able to figure it out? That is a bit complicated to answer in a comment box. You could ask me through my Facebook.com/ProfRobBob fan page.

...that's for sure:)
I love it, that you are showing boths methods are pretty much the same. no one else has explained that on youtube or at school.
THE BEST CALCULUS VIDEOS ON THE INTERNET!
Thank you!

Go pass that Calc final like BAM!!! Soho Yankee Glad I could help and it's good to see you are still watching and learning!
(funny...that's about how many days I have left before xmas break, wooo whooo:)
BAM!!! Yeah if you could do the Calculus 2 playlist series that will benefit not only me, but other students as well.....
Well done. A very comprehensive explanation of U-Substitution. Thank you!!!

I really like the 6 listed steps at the end of this video. I hope to see more of that in your vids.
I will do my best:) Thank you for watching and your feedback.

:(
Don't give up...practice, practice, practice then next thing you know...BAM!!!
Incredibly helpful, thank you!
+tomaitoe :)
The interesting thing about the last example is that it has three solutions. Two, which were shown, and the third being,
-cos (8x)/16 + c.
A little Power Reducing formula work there:) Thank you!
is this variations of substitution method?
Hey Shane…I'm using U substitutions to show how to make the problem match the integration rules that you are learning.
Not sure I completely understand your question:( Are you thinking about what you learned when doing the chain rule? My book teaches u substitution as a suggestion for those types of problems too.
Wow I`m really excited to learn integration techniques now! Thank you!!!
And I'm excited to be the one helping to teach you:)

I am having trouble with trig intergals---- I understand the rest, espically pie*(sinpiex)dx please help
Set a u substitution and Let u = Pi X and du = Pi dx
The problem im doing is 2x (-x+1)^(1/5), my teacher gave us the answer key to check our work and I got one part of the answer, 5/3 (-x+1)^(6/5) but I can't get the other part. Help :)?
Sorry I never got to your question. Were you able to figure it out? That is a bit complicated to answer in a comment box. You could ask me through my Facebook.com/ProfRobBob fan page.
