(1+tan 6 + sec 0) (1 + cot e-cosec ) aka : (A) O (B) 1 (C) 2

(1+tan A+sec A)(1+cot A-cosec A)=

(1 + cot A — cosec A) (1 + tan A + sec A) = 2 .

(1+tan theta+sec theta)(1+cot theta-cosec theta) = ? (a) -1 (b) 0 (c) 2

( 1 + tan theta + sec theta ) ( 1 + cot theta - cosec theta ) =

Prove that (1+tan A+sec A)(1+cot A-" cosec A")=2
