16:00 Prof.V How can occur two global values in each function?! In fx = x^2 [-1,1] >>gives me two global max but the function increasing without boundary, so there is no global exterma, I understood..
@11:54 why do you set 25-t^2 less than or equal to 0? Why would you want values less than zero? Wouldn't you just need to divide by zero to get values where F'(t) DNE
Yes that would be fine for this function since the domain is already restricting values that would make the radicand negative, so you just need to worry if the denominator was 0. 👍🏻
B/c critical value has 2 conditions 1- the derivative of the orginal function =0[occur if the numerator =0] 2- the derivative does not exist [occur if the denominator undefined] 3- the value of critical value should be in the Interval domain(I)
I can’t understand math without you ❤
You have taught this so well, thank you! 🙌
You are very welcome!

all the way from UAE thank you
You’re so welcome! ☺️🫶🏻
Thank you, thank you, thank you!!!❤❤🫂🫂
You are so welcome!
why do we not plug in the values in the actual function? e.g. (-1 - 1) ^3 . @4:21 thank you!

why did we not take underoot 25-t^2=0? why did we set the numerator=0 and not denominator?
