Oh man, I don't even know where to start. You and Prof. Leonard are the best calc teachers I have seen in this world that are still alive. You really show the understanding of "how to use Feynman's technique" when explaining the topic. Bravo!
Thanks for the compliment Pranav...I'm glad I'm still alive to reply...lol Seriously...thanks for your continued supporting please sub and keep sharing this channel and your experience with everyone:)
ProfRobBob I will and I just took the test on Thursday and I did good for the most part but we had two parts a calculator and a non calculator and I took too long for the calculator part so I didn’t have enough time for the other but I can tell you that I knew how to do the problems I just didn’t have time
I never usually leave comments, but you deserve one! Whenever I am confused with math (which happens more often than I'm willing admit) I come watch your videos. You explain things in simple terms and still keep me engaged. Thank you so much! Wish I had you as my teacher.
+Kendall Oliver you're welcome and thanks for taking the time to share your appreciation, it's always nice to hear that you are making a difference...at least I can be your TH-cam teacher! Glad the videos are helping so much...please take the time to like, subscribe and share my channel with everyone in order to help these free educational channels keep growing and remain free for everyone:D
Again, left class with a vague understanding of increasing/decreasing and max/min functions..Went straight to the computer lab to see if Mr. ProfRobBob has a helpful video on this topic and voila! What you're doing is beyond math, it helps people understand tough concepts and get good grade to progress further to that degree! You rock man!
THANK YOU Constantine T for your complimentary comment, your repeated support and looking to my channel first for help:) Next time you're in the computer lab maybe you could print and post one of my flyers from my website for me! (available at profrobbob.com) In the mean time please continue to help my channel groW by sharing your learning experience and my channel with everyone and "Spreading the Word" thru social media:D Help us reach our goal of 100,000 subscribers by 2015...BAM!!!
Man every time i watch your videos you just always have a different easier way to remember than what other teachers teach. Like in this how instead of creating a chart you just create the intervals in parenthesis rather than a big chart like my teacher did and under each one write the positive or neg. Or in your first basic log video where you say a log is the base^answer = exponent, whereas other teachers and books teach you to just remember the log is something like b^c=a. It's so much easier when you know and understand it rather than just memorize formulas!
"3.9, 3.99, 3point na-na na-na na-na na-na" BATMAN!!! 🎵🎶BATMAN!🎵🎶 Haha!! 😂 (I couldn't resist 😁 lol) You've helped me a LOT!! (I have a great Calculus teacher too,) but I need to hear stuff more than once...to pause, ponder 🤔 & digest!
LOL...that's awesome!!! Thanks for taking the time to share your appreciation and honesty and thanks for choosing my channel to do that studying with. Please share this channel and your story with your Calc teacher just in case they want to share it with other students like you in the future...and thank them for doing such a great job as a teacher, we can never hear that too often...BAM!!!
I've just come across this channel. I am really amazed by your way of explaining and your focus on the small steps while solving problems that usually are not explained on other channels. Thank you much
You are so welcome and thanks for studying, subbing, liking and learning from this channel...please share these free educational channels that help you, that's how we all keep growing:D
ProfRobBob your videos are awesome and they are a big help + the occasional humor makes math so much less boring. I wish I could attend one of your lectures in person. Keep up the great work! You're awesome.
Thanks for watching and subbing Tyshon Thompson and taking the time to share your experience and appreciation!...if you're ever in St Pete feel free to drop by my class and sit in :)
Thanks for taking the time to seek outside help and choosing my channel to study with! Please share this free resource with your on-line teacher or wherever you sigh up for this class with:D
It's hilarious that I pay some big university professor to teach me calc., but I just end up coming to watch your videos instead because you actually explain the math in simple terms. Thank you so much for posting these videos!
Thanks for watching, subbing and sharing your appreciation! Sounds like a perfect time to share this free resource with your professor for all the current and future student at your university...BAM!!!
Thanks for studying with Tarrou's Chalk Talk...after you pass that midterm like BAM!!!...please take the time to like, sub and share this channel with the rest of your class and friends too:D
Adriana Gomez You are so welcome! ...and thanks for your continued support, please be sure to share my channel with all your friends and classmates looking for math help:D
WhoooHoooo...welcome back! Where did the summer go?!!! Does this mean you're using my videos again and still flipping?! I hope you have a spectacular school year:) Keep in touch and let me know how things are going from time to time.
I saw them used a little bit in my summer AP training. I am teaching Calc life for the first time this year, so suggestions are appreciated. If you can send a picture...I have a Facebook fanpage you could send me a personal message through. I will try to help as much as I can:D I am having a blast with my Calculus class this year...except I also am teaching PreCalculus, AP Statistics, and a remedial math class while making brand new plans for Calculus!!!
Wish me luck for my test on this monday ! Hope this will help ! And you're awesome ! I like your videos ! Im looking forward to the next video ! Keep it up sir ! :)
You're welcome Rogina Gerges and THANK YOU for taking the time to study and for choosing my channel to watch, learn from and sub to! After you pass that test please be sure to share your experience and my channel with your friends, class and teachers as an additional study resource to help keep raising those GPA's...BAM!!!
Have you seen the sign charts to help with these types of problems? If not, I can find a way to send you my notes on them. It makes the process in this and the 2nd derivative test a lot easier when finding the signs and determining what goes where. I still need your help getting through calculus though. Thank you so much for your help. I watched your extrema video before class and I actually had an idea of what I was learning about!
LOL SFUManiac...I love your calculations!!! Thanks for watching & subbing to #ProfRobBob ...and I hope you have posted my channel info in the campus math lab for me too:)
Thank you for all of your videos. They've greatly assisted my studies. I wanted to point out a contradiction of your written Test for Inc and Dec F and the one written in Larson Calculus 10th ed. It's the first If... If f prime of x is greater than zero for all x in (a,b)...you've written a closed interval while in the text here there is an open interval. Would this change the condition of the derivative? Or would it have no significant impact in it's application when we are in fact seeking relative rather than global max/min? It would seem to exclude the concept of the global max/min. Because we're employing the concept to find limits within a function, I don't think it's a big deal, but I want to make sure. Thank you again.
THANK YOU…for commenting, watching, supporting and subscribing but OMGoodness, I'm teaching AP Calc for the first time this year and keeping up with those videos along with 3 AP classes and 4 preps and life…I'm sorry to say, there is no time right now for Calc2 but they will come, just not this year:( In the mean time I do appreciate the support and please tell others where to find me:)
Videos are phenomenal, however I am confused on how to set a trigonometric function to zero when there are multiple trig functions involved with the derivative. Ex: y= (theta) + sin(theta) + cos(theta). Your assistance would be most appreciated!
If you are not allowed to use your calculator to solve these types of problems you will probably need to use Trig Identities to rewrite the equation so there is only one trig function (variable). Like cosx=sqrt(1-(sinx)^2)
Question. Can there just be a hole at negative and positive 2? Wouldn't that be another conceivable way of drawing the graph rather then having an asymptote at the respective x-values?
When the numerator and denominator of a rational function are just polynomials, you will have vertical asymptotes where the denominator equals 0 unless those factors (zeros) can be cancelled with a factor(s) from the numerator.
at 21:40 y prime in the denominator is not x^2 -4 as you say .Its (x^2-4)^2. So when you solve for your critical numbers they are the wrong numbers. I graphed the equation in my caculator and it does't look like anything you came up with. What gives?? ?????? Please get back to me
+Jake Kipp ABSOLUTLY!!!! That's why we have one, but you are the first person who has offered to print and post it...and if you remind everyone of those 15,000 students to subscribe when they watch, we might actually reach our goal of 100,000 subscribers before the end of the year...BAM!!!

Just keep practicing...maybe do some self timing on the calculator and next time I'm sure you'll feel more confident and pass that test like BAM!!!
