Step-by-step explanation
2.LHS
sinA/cotA+cosecA
=sinA/(cosA/sinA)+(1/sinA)
=sinA/(cosA+1/sinA)
=sin²A/1+cosA
=1-cos²A/1+cosA
=1-cosA
RHS
2 + sinA/cotA-cosecA
=2 + sinA/(cosA/sinA)-(1/sinA)
=2 + sinA/(cosA-1)/sinA
=2+ sin²A/cosA-1
=2- sin²A/1-cosA
=2- (1-cos²A)/1-cosA
=2-(1+cosA)
=2-1-cosA
=1-cosA
LHS=RHS
