i have the integral $\displaystyle \int csc(\pi x - 1) dx$
if i say $\displaystyle t = \pi x - 1 => dt = \pi dx$
so i make the substitution leaving $\displaystyle \frac{1}{\pi}\int csc(t) dt$
but ive no idea how to integrate cosec?

$\displaystyle \int csc(x)dx = ln |csc(x)-cot(x)| + C$
I had to look it up in a table of values.

Hope that helps.
