Answer:

cot A + tanA

= 1/sinA*cosA

coseca = 1/SinA

sinAcosA/sinA = cosA

Hii..dude..♥️

Solving LHS ,

= COSECA / COTA + TANA

= COSECA / (COSA / SINA + SINA/COSA )

= COSECA/(COS^2A+SIN^2A)/SINA.COSA

= 1/SINA/1/SINA.COSA

= SINA.COSA/SINA

= COSA

= RHS

Therefore , LHS = RHS

Hence , verified .
