1. ## trig integral

I tried this integral but Im not sure I got the correct answer. I got cos(1-x)+C

Integral sin(1-x)dx

2. You are correct

as nzmathman said, you are correct. you could check for yourself though. if you differentiate you answer, you should get the original integrand. since (by the chain rule) $\frac d{dx}[\cos(1 - x) + C] = \sin (1 - x)$, you are correct
