Hi,

I'm I on the right track with this problem?

1. The problem statement, all variables and given/known data

Evaluate the Indefinite Integral

2. Relevant equations

integral of sin t sec^2 (cos t)dt

3. The attempt at a solution

integral of sin t sec^2 (cos t)dt

Let u = cos t

du/dt = sin t

dt * -sin t = du

dt = du/-sin t

integral sin t sec^2 (u) dt

integral sin t sec^2 (u) du/-sin t

- integral of sec^2 (u) du

- [tan (u) du ] + c

- tan (cos t) + c
