Question

Prove that tanA/1+secA-tanA/1-secA=2cosecA
​

Answer 1

Answer:

$\mathrm{Prove\:}\frac{\tan \left(a\right)}{1}+\sec \left(a\right)-\frac{\tan \left(a\right)}{1}-\sec \left(a\right)=2\csc \left(a\right):\quad \mathrm{False}$

Step-by-step explanation:

$\frac{\tan \left(a\right)}{1}+\sec \left(a\right)-\frac{\tan \left(a\right)}{1}-\sec \left(a\right)=2\csc \left(a\right)$

$\mathrm{The\:two\:sides\:are\:not\:equal}$

$\Rightarrow \mathrm{False}$
