Hey Friend :-)

Here is your answer

=> 1 / (cosecA - cotA) . . . . . . . . . . .multiply top & bottom by (cosecA + cotA) 

=> 
(cosecA + cotA) /(cosec^2A - cot^2A) . . . . . . .use cosec^2A = 1 +                                                                                                                        cot^2A 

=> (cosecA +cotA) / 1 

=> cosecA + cotA

RHS = LHS 

Hence, proofed.

Hoping it helps

Thanks :D

RHS 
1 / (cosecA - cotA) . . . . . . . . . . .multiply top & bottom by (cosecA + cotA) 

(cosecA + cotA) /(cosec^2A - cot^2A) . . . . . . .use cosec^2A = 1 + cot^2A 

(cosecA +cotA) / 1 

cosecA + cotA 

RHS = LHS 
QED

HOPE IT HELPS
