Question

Another integral problem!

Answer 1

So I know that the integral is -cos^3 (x) / 3 + c for the integral of cos^2 (x) * sin(x)

Answer 2

So the first part would be zero because 2/3 - 2/3 is 0

Answer 3

I mean 1/3 - 1/3

Answer 4

But what about the second part? Wouldn't that just be adding 1/3 and 1/3 together to get 2/3?

Answer 5

For the second part, you need to honor the absolute bars,
for what values of `x`, is the expression `cos^2x*sinx` negative ?

Answer 6

When x is pi/2 to 3pi/2
