3 sin ^2 t cos t (i) + 3 sin t cos^2 t (j) + 2 sin t cost (k)(adsbygoogle = window.adsbygoogle || []).push({});

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
