I'd like to find the integral of this in terms of re(f(x)) and im(f(x)). Please show some steps, this is not homework.

$$\int arg[f(x)]dx$$ x∈ℝ

Pardone my ignorance, but can you just explain what re(f(x)) and im(f(x)) are,just so we will be on the same page, and thus avoid any possible confusion.
