Question

The value of expression $tan\theta -cot\theta at\theta ={30}^{\circ }$ is 1.

• A. True
• B. False

Answer 1

The correct option is B False

$Valueoftan\theta at\theta ={30}^{\circ }is\frac{1}{\sqrt{3}}$
and the value of $cot\theta at\theta ={30}^{\circ }is\sqrt{3}.$
$So,tan{30}^{\circ }-cot{30}^{\circ }=\frac{1}{\sqrt{3}}-\sqrt{3}\ne 1$.
