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
