Question 921536
{{{cot(theta) = cos(theta)/sin(theta)}}}



So {{{cot(theta)}}} is undefined when {{{sin(theta) = 0}}} due to the division by zero error.



{{{sin(theta) = 0}}} is true when {{{theta = 0}}} or {{{theta = pi}}}. Use a unit circle to see this.



So if {{{cot(theta)}}} is undefined, then {{{theta = 0}}} or {{{theta = pi}}}
