(17.)/(" Гд ")quad 17.(1+tan^(2)+sec theta)(1+cot theta-cosec theta)

(1+tan theta+sec theta)(1+cot theta- cosec theta) is equal to

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

(1+tan theta+sec theta)(1+cot theta-"cosec "theta) is equal to :

" (2.) "tan theta+cot theta=sec theta cosec theta

Choose the coorect option. Justify choice : (1+ tan theta + sec theta)(1+ cot theta - cosec theta) =

Evaluate the following : (1 + tan theta + sec theta) (1 + cot theta - cosec theta)

The identity (1+ tan theta - sec theta)(1+ cot theta - "cosec"theta) not equals

tan theta+(1)/(tan theta)=sec theta cosec theta

(2+tan^2 theta+ cot^2 theta)/(sec theta cosec theta) is equal to : (2+tan^2 theta+ cot^2 theta)/(sec theta cosec theta) का मान किसके बराबर है ?
