Question

proof of this question

Answer 1

aarti It's simple

sec^2 A = 1+ tan^2 A
and cosec^2A = 1+ cot ^A

value put kr do answer aa jayega

we are given √sec^ A + cosec^2 A = √1+tan^A + 1 + cot^A 
     
               =  √2(1) + tan²A + cot^A
               = √tan^A + cot^A +2cotA tanA       {∵ cot A * tan A = 1}
               = √(tan A + cotA)² = tan A + cot A = RHS
