$\lim_{x \rightarrow \pi} \cot(x)$

$\cot(\pi)=\frac{\cos(\pi)}{\sin(\pi)}$ is undefined because the denominator is zero. if the numeratore was also zero you would have to do more work to find the limit, but since the numerator is -1 you get something that looks like $\frac{-1}{0}$ so there will be no limit

thanks should have been able to recognize that myself
