Question

prove this.................

Answer 1

$= \ \textgreater \ \sqrt{ \frac{cosecA+1}{cosecA-1} }$

$= \ \textgreater \ \sqrt{ \frac{cosecA + 1}{cosecA - 1} * \frac{cosecA+ 1}{cosecA+1} }$

$= \ \textgreater \ \frac{(cosecA+1)^2}{cosec^2A - 1}$

$= \ \textgreater \ \sqrt{ \frac{(cosecA+1)^2}{cot^2A} }$

$= \ \textgreater \ \frac{cosecA+1}{cotA}$

$= \ \textgreater \ \frac{ \frac{1}{sinA} + 1 }{ \frac{cosA}{sinA} }$

$= \ \textgreater \ \frac{ \frac{1 + sinA}{sinA} }{ \frac{cosA}{sinA} }$

$= \ \textgreater \ \frac{1 + sinA}{cosA}$



Hope this helps!
