LHS= (SinA +1/CosA)² +(CosA+ 1/SinA)²
=((SinACosA +1)/CosA)²+((SinACosA +1)/SinA)²
=(SinACosA +1)²/Cos²A +(SinACosA+1)²/Sin²A
=(SinACosA +1)² {1/Cos²A +1/Sin²A}
=(SinACosA +1)² {Sin²A +Cos²A /Sin² A Cos² A}
=(SinACosA +1)² {1/Sin² A Cos² A)
=( SinA Cos A/SinA Cos A +1/SinA Cos A)²
=(1+CosecA.SecA)²
=RHS
Hence proved
=((SinACosA +1)/CosA)²+((SinACosA +1)/SinA)²

=(SinACosA +1)² {Sin²A +Cos²A /Sin² A Cos² A}
