3 sin ^2 t cos t (i) + 3 sin t cos^2 t (j) + 2 sin t cost (k)
I have to take the antiderivate for each Vector.
Then I have to evaluate it from pi/2 to o.
I'm confused because I can't use a trigonometric substitution.
Cosine is odd for the I vector but I can't substitute 1-sin^2 t in for it. Because it has to be cos^2 t
