Consider the function:(adsbygoogle = window.adsbygoogle || []).push({});

g(z(t)) =i*f '(c+it)/(f(c+it) - a)

Where {-d <= t < d}

If we let z = c+it

By change of variables don't we get:

Line integral of g(z(t)) =iln[f(c+it) - a]

evaluated from t = - d to t = d?

note: ln is the natural log.

Inquisitively,
