If you do not know what substitution to make, try reducing the integral step by step, using a trial substitution to simplify the integral a bit and then another to simplify it some more. You will see what we mean if you try the sequences of substitution.
a. u = x - 1, followed by ν = sin u, then by w = 1 + ν2
b. u = sin (x - 1), followed by ν = 1 + u2
c. u = 1 + sin2 (x - 1)
J V1 + sin(x - 1) sin (x - 1) cos (x - 1) dx
