Question

Integral and u sub problem

Answer 1

I think the answer is True.

Answer 2

true,u=cos(x)

Answer 3

since u = cos(x) and x = the limits of integration; we can simply rephrase the limits by letting them speak the language of u instead of x

Answer 4

the thing is, their limits tend to be transposed to me

Answer 5

cos(0) = 1 , not 1/2

cos(pi/3) = 1/2 ; not 1

Answer 6

by flipping the limits you negate the results

Answer 7

Yeah, that's what I thought. They've been flipped, but I was like "seems legit"!

Answer 8

so the results arent "equal" or "equivalent" perse

Answer 9

15 = -15 is false .... but 0 = -0 is true so it depends on the outcome id spose :)
