Question

Help finding critical points of integral

MEDALS!! (;

Answer 1

I tried to find out if there were no critical points by plugging in 0 but it turns out that there are...

Answer 2

did you differentiate wrt x?

Answer 3

ok, that makes more sense. So i follow the same steps of finding the critical points for integrals as I would for derivatives. No new trick eh?

Answer 4

no

Answer 5

@sourwing Im having a tough time figuring out what the critical points are. I tried out 0,5243/288,-5243/288 but they aren't correct

Answer 6

htf did you get number?

Answer 7

wolfram alpha

Answer 8

WTF! it's -2 and 2

Answer 9

how did you get that I went ahead and set the denominator to 0 and got some funky answer.

Answer 10

8 + cos^2(x) will never be equal to 0. So set the numerator equal to 0

Answer 11

ok thanks

Answer 12
