Answer:
Consider angle theta as A
(sinA + Sec A)² + (cos A + cosec A)²
[ (SinA CosA + 1)²/CosA ]² + [ (CosA SinA + 1)² / Sin²A ]
(1+ SinA CosA)² * [1 / Cos²A + 1/sin²A ]
(1 + SinA CosA)² * [ Cos²A + Sin²A]/ [cos²A * Sin²A ]
( 1 + SinA CosA)²/ (cosA * SinA)²
[ 1/cosA * 1/sinA + 1 ] ²
= [ Sec A Cosec A + 1 ]²
