Question

lim x>pi cot(x)

Answer 1

\[\lim_{x \rightarrow \pi} \cot(x)\]

Answer 2

\[\cot(\pi)=\frac{\cos(\pi)}{\sin(\pi)}\] 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

Answer 3

thanks should have been able to recognize that myself
