Step-by-step explanation:
sinA+sinAcot^2a=cosecA
Sol->
=>sinA+sinAxcos^2A/sin^2A=cosecA
=>sinA+cos^2A/sinA=cosecA
=>(sin^2A+cos^2A)/sinA=cosecA
=>sin^2A+cos^2A=cosecA×sinA
=>sin^2A+cos^2A=1/sinA×sinA
We know sin^2A+cos^2A=1
so,at LHS we write 1
=>1=1
As,LHS=RHS.Hence Proved that sinA+sinA cot^2A=cosecA
