Step-by-step explanation:
L.H.S:
=(1+tan A/sin A)+(1+cot A/
cosA)
=(1+(sin A/cos A)/sin A)+(1+(cos A/sin A)/cos A)
=((cos A+sin A)/cos A. sin A) +
((sin A+cos A)/cos A.sin A)
=(cos A+sin A+cos A+ sin A)/
cos A. sin A
=(2cosA+2sinA)/cosA.sinA
=(2cosA/cosA.sinA)+(2sinA/
cosA.sinA)
=2 cosecA+2secA
=2(cosecA+secA)
LHS =RHS
Hence proved
