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

    Integral sin(1-x)dx

    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
