Question : If the value of $\operatorname{cosec} A + \cot A = m$, then the value of $\operatorname{cosec} A - \cot A$ is:

Option 1: $\frac{1}m$

Option 2: $m$

Option 3: $\sqrt{m}$

Option 4: $m^2$

Team Careers360 25th Jan, 2024

Correct Answer: $\frac{1}m$


Solution : Given: $\operatorname{cosec} A + \cot A = m$
We Know that, $\operatorname{cosec}^2 A - \cot^2 A = 1$
$⇒(\operatorname{cosec} A - \cot A)(\operatorname{cosec}A + \cot A) = 1$
Substituting $m$ for $\operatorname{cosec} A + \cot A$, we get:
$\therefore\operatorname{cosec} A - \cot A = \frac{1}{m}$
