Question

How do you find the value of $cot0°$?

Answer 1

Calculate the value of trigonometric ratio at given angle:

Let $x$ be the value of $cot0°$.

$\therefore x=cot0°$

$=\frac{\cos 0°}{\sin 0°}$ $[\because co\mathrm{t\theta }=\frac{co\mathrm{s\theta }}{si\mathrm{n\theta }}]$

$=\frac{1}{0}$ $[\because cos0°=1;sin0°=0]$

$=\text{undefined}$

Hence, the value of $cot0°$ is undefined.
