cot theta+tan(90+theta)+tan(100+theta)+tan(360-theta)=0

Which of the following statement is true? (A) sin theta=cos (90-theta) (B) cos theta=tan (90-theta) (C) sin theta=tan(90-theta) (D) tan theta=tan (90-theta)

cot theta=tan theta if theta=

(cot theta)/(cot theta-cot3 theta)+(tan theta)/(tan theta-tan3 theta) is equal to

(cot theta)/(cot theta-cot3 theta)+(tan theta)/(tan theta-tan3 theta) is equal to:

Prove : (tan theta) /(1- cot theta) + (cot theta)/ (1-tan theta) = 1 + tan theta + cot theta

If 11theta=90^(@), then the value of the expression tan theta tan 2 theta tan 3 theta tan 4 theta tan 5 theta tan 6 theta tan 7 theta tan 8 theta tan 9 theta tan 10theta is equal to-

What is the value of (tan (90^@-theta) sec (180^@-theta)sin(-theta))/(sin (180^@+theta) cot (360^@-theta) "cosec"(90^@-theta)) ?

cot theta tan(90^@-theta)-sec(90^@-theta)cosec theta+sqrt3 tan12^@ tan 60^@ tan78^@=2

What is the value of [tan^2 (90- theta)-sec^2 (90 - theta)] tan^2 (90- theta) cot^2 (90 -theta) ?

(sin(-theta)tan(90^@+theta)tan(180^@-theta))/(sin(180^@-theta)cos(90^@-theta)cos360^@-theta))=sec theta cosec theta
