Question

True or false for the integral:

Answer 1

I think it's false, because there's a mistake on the right integral. The lower value is on the top.

Answer 2

@ghass1978 what do you think it is?

Answer 3

sorry i was away,its true

Answer 4

looks true to me as well
make the u- sub
\[u=25-x^2, -\frac{1}{2}du=xdx, u(0)=25,u(3)=16\]

Answer 5

I came up with the same thing using u-sub, but why is the lower value on the top of the integral?

Answer 6

because your sub is
\[u=25-x^2\]

Answer 7

so when you replace x by 0 you get 25 and when you replace x by 3 you get 16
just works out that way

Answer 8

ohh...I figured that it wasn't allowed. Thanks!
