Let's say I have an integral from -pi to 0 of csc(x)dx(adsbygoogle = window.adsbygoogle || []).push({});

This obviously is equal to ln|csc0 - cot0| - ln|csc(-pi) - cot(-pi)|

But csc is undefined for both these values., so is this integral not able to be evaluated? Or can we just let csc0 and csc(-pi) be equal to 0? Oh so confused. Please help.
