queation is wrong ...........,

Answer 2

Answer:

LHS

= SinA/cosA/(sec square A) square+cosA/sinA/(cosec square A) square

= sinA/cosA(1/cos four A)+ cosA /sinA(1/sin four A)

cancel both the power . remaining square is.

= sinA/ cos A(cos cubeA)+ cosA /sinA(1/sin cubeA

= sinA/cosA/(sec square A square)+cos A/sinA/ (cosec square A square)

= sinA cos cube A+cosA.sinA

= sinA. cosA( cos square A + sin square A)

= sinA.cosA (1)

= sinAcosA (proved)
