Question

$cot\left(0\right)\frac{1}{tan0}$
Express with sin, cos and tan (i)

Answer 1

$cot\left(0\right)\frac{1}{tan0}=\frac{1}{tan0}.\frac{1}{tan0}\frac{1}{tan0}.\frac{1}{tan0}=\frac{1}{ta{n}^{2}0}\frac{1}{ta{n}^{2}0}$
Use the following trivial identity tan(0)=0
$=\frac{1}{0^2}$
$=\frac{1}{0^2}$=Undefined
= Undefined
