x->pi from
the right

Answer 1

what is cot(pi) ?
@maggielucci

Answer 2

Remember the equation:
\[\cot x = \frac{ \cos x }{ \sin x }\]
which is continuos @
\[x = \frac{ \pi }{2 }\]
SO ,
\[\lim_{x-> \frac{ \pi }{ 2 }} \cot x = \lim_{x-> \frac{ \pi }{ 2 }} \frac{ \cos x }{ \sin x} = \frac{ 0 }{ 1 } = 0 \]
0 or infinity

Answer 3

good @Adjax

Answer 4

it's only pi @Adjax

Answer 5

so it would be positive infinity
