I thought these were all bots ngl. But it’s true she basically explains how you should go about optimization. It’s really hard for professors to even explain it so they just go on along chugging numbers. Thanks woman 🙏🏾
Honestly, you are amazing, so clear and to the point but not sparing explanation. I am super bad at math and I got every single step and was not lost once. I hope you get the recognition you deserve. Very very good teacher! Thank you so much.
what has taken me a week to try and understand took me 18 min thanks to your video. I am referring my classmates to your channel. thanks sooooooo much for your help!
First teacher I have seen that seems to understand the main problem comes from setting up the two equations. Good stuff, I have a test over this in the morning and your explanation helped a bunch! 🤞
Thank you for your explanation of optimization problems. I watched this after going over this in my last lesson and it really help solidify the subject matter. I didn't really notice I was plugging into two equations every time and now that i know what to look for, I feel confident. Thank you again!
The first example is better understood if you use example Area = x*y = 198. Find minimum perimeter of a rectangle 2(x+y) which has Area(x*y) = 198 . Also do you know where I can find a Simplex program for multivariable linear optimization. Thanks.
Thank you so much for this video I recently missed 2 periods of my honors calc class and this video was extremely helpful I have a test tomorrow and I am 100% able to do my review sheet! Great video
The derivative is equal to zero at relative minimums and relative maximums. Knowing this, is it safe to conclude that the answers you obtain in the first problem are both minimums? Is it possible that one could be a maximum?
HI.. Its just so awsum,, You are going very good Mam :) (Y) Maxima and Minima the first derivative test optimization Techniques of integration (power of sin and cosine, Trignometric substitutions, integration by parts, Rational functions, etc) Differentital equations Coshy Problems
Great video again. I have one question. I understand why we have to set the derivative equal to zero to get the minimum, but what exactly does this mean? I can see that the derivative (the slope) would be a line parallel to the x axis and therefore the slope would be 0 and that is how far I can go to understand. Hope you understand my question. Thanks again Jenn
If the slop equals zero at that point it means that slop might be changing direction at that point. If it is that means it is either coming up from the left and down to the right in which case I'd be a max or it be coming down from the left and going up to the right which makes it a min. To find out which it is you take the second derivative at that point and if it is positive it's a min. If it is negative then it is a max.
The first derivative rule tells us that when the firs derivative is equal to 0, there is a local maximum or minimum. Think of it like there either being a giant U like shape or an upside down shape. Imagine putting a dot on the bottom of the U, this is your minimum on a concave up part of the graph. If you were to flip that U upside down and put a dot on the top (Like a peak of a mountain, almost, except curved) that's your local maximum. You were so right in saying that the derivative line is parallel to the x-axis!! That's because if you draw a tangent line at either one of those 'dots' on the U/upside down U graphs, it would be parallel to the x-axis!! Hope you understood!

Excellent explanation. Made a seemingly impossible concept extremely understandable.
+Aziz Elbasheir :)
so I have watched about every video on optimization and I couldn't do it at all until I watched this video. Thank you. Don't ever stop teaching math.
Thank you so much for your kind words. :-)
Woah! This is crazy!
I watched the video up 2:19 and now I can solve any optimization problem.
Thank you so much.
Love it...
no kidding!
my left ear enjoyed this :). also great video thank you!
+The Circle got scared thouught my right earbud broke haha

thank you so much. I don't think it is possible for anyone to simplify it more than you have.
Unbelievable !! I wish I'd had teachers like this in college who are so clear and logical, she's like a walking syllogism !! thanks!
You explained so well my kid brother will even understand what you're doing.
Honestly, you are amazing, so clear and to the point but not sparing explanation. I am super bad at math and I got every single step and was not lost once. I hope you get the recognition you deserve. Very very good teacher! Thank you so much.

THANKYOUUU VERY MUCH! THIS HELPED ME A LOT FOR OUR CALCULUS TEACHER AINT DOING HIS JOB AND IM TOO LAZY TO READ MY BOOK. ILYSM.
Omgg this was amazing! You explain the concept so clearly. I can actually do optimization now.
Thank you for your explanation of optimization problems. I watched this after going over this in my last lesson and it really help solidify the subject matter. I didn't really notice I was plugging into two equations every time and now that i know what to look for, I feel confident. Thank you again!
You are an excellent teacher. Thank you so much for these free videos.
Hi Cooked Vegan Fitness - Thanks! I'm so glad they helped. :)
Thanks a lot for clear explanation. Any more videos on calculus & linear algebra coming? See forward to it!
used your method to find max area of a rectangle bound by a certain function. helped me out a lot. thanks!
+Brad Ingram - Rock ON!
The Dora of Calc teachers and I mean that in a good way great explanation!
3 months into calc and I want to jump into the ri era and float away. None the less, great video.
WOW I wish my college professor could explain calculus like you ... would make my life much easier!!!!
Thanks for the video.
Glad you enjoyed the video!
Thank you so much! finally helped me understand the difference between solving one for the max and one for the min
This was so amazing! So clear and easy to understand! THANK YOU
Thanks for the explanation, I really loved how much you made it simple!!
you have summarized it nicely, pretty easy to be digested, keep on good work. it helped a lot.
your one smart cookie. somehow you turned something aversive into an enjoyable hobby
Hey Nate - Thanks a lot. That's cool way of looking at it. :)
Best videos to help you with calculus all over youtube
Thank you so much Syed!
Thank you so much for this video! It really helped me understand optimization once you broke it down into three steps and made it ALOT less daunting!
Love your video! You are very clear and easy to understand. I will go to your videos for help in the future. Thank You!
Thanks Jessica!
Why couldn't you have been my calc teacher. it makes way more sense.
Thank you so much! I finally understand optimization so much better now thanks to you :D
Very Helpful Thank you! Keep up the great work, this is much appreciated.
The first example is better understood if you use example Area = x*y = 198. Find minimum perimeter of a rectangle 2(x+y) which has Area(x*y) = 198 . Also do you know where I can find a Simplex program for multivariable linear optimization. Thanks.
Really wish my teacher explained this as clearly as you do
None of her markers have caps
lol
😂😂
00:30 "...optimize my checking account..." 🤣🤣 finally! I'm watching the right YT video!
Simple and clear!!!Great job!Thank you for your video!!!
Thank you so much for this video I recently missed 2 periods of my honors calc class and this video was extremely helpful I have a test tomorrow and I am 100% able to do my review sheet! Great video
+Nicole Michelle You're welcome!
Great video, my left lobe can optimize anything now!
I appreciate your quick joke at 12:10 on minimum ink in the green dry-erase marker: "Oh my goodness, it's a minimum!" Right to the situation! :-)
haha - glad you enjoy my quirks.... :)
Thank you for you fantastic explanation. I love your energy. I will definitely consult your website.
thanks to you i passed my finals :)
That's great news!! Congratulations!

Woah!!! you are amazing. You just made it simple for me. Thank you
Excellent instruction. Thank you.
Hey Bill Holt - thanks for the compliment!. :)
Dear professeur, is optimisation calculus a part or an exception of infinitésimal calculus ?
Awesome explanation! I wish my teacher is more like you~
This was really helpful, she explained this concept very well (I only wish I had watched this before my exam lol)!
I'm gonna show my grandkids this video when they're struggling with optimization.
I learned so much, thank you i really appreciate it !!!!!!
thank you so much!

Thanks for making this into a short video! :)
good video... when i watched it, i only got left audio out of the video--dunno if this is a problem on my end or just the video
Hi Nikolaus Smith-Simmons - not your end, the video was initially encoded in mono. :-)
Great video.
John Brasely :-)
Well done.
im 10 years old and i can understand calculus EASILY
can you do a series on derivatives, implicit differentiation and using log as well e^X in derivatives
Thank you so much. It really helped.
how are we able to determine the domain?
This is soooo helpful, Thank you for the great video! really helps, better than anybody else! :)

amazing! thank you for your three steps for optimization!
Hey Linda Rubio - Your Welcome!! :)
Thank you so much! I love your videos
Thanks so much!
But how do you determine if it's a maximum or minimum
great exercise.
veryy kool
nice explanation
your brilliant, so enthusiastic.
WOW - so humbled by your comments... :-)
love, love, love this.
:-)
i just subscribed for the month just for my finals next week.
i will do the 6 month in January 2017 for calculus 2.
your are awesome
i learned my lesson taking calc over the summer too. I nearly blacked out during the final
I enjoyed it
Why can't product be the product of three numbers? Is optimization only for 2 variables?
thank you very much
Do you know how to use a matlab code to solve complex optimization problems?
