(11i)sin90=sin theta

If 90^(@)

Simplify: (i) (cos theta)/(sin (90^@ + theta)) + (sin (-theta))/(sin(180^(@) + theta)) - (tan(90^(@)+theta))/(cot theta)

Prove the following identities: (i) costhetasin(90^o-theta)+sinthetacos(90^o-theta)=1 (ii) (sin(90^o-theta))sintheta/(tantheta)-1=-sin^2theta (iii) (sin(90^o-theta)cos(90^o-theta))/(tantheta)=1-sin^2theta

What is the simplified value of sin^(2) (90- theta) - [({sin(90-theta) sin theta})/(tan theta)] ?

sin90^(@)=sin theta Find all the possible values of theta.

Prove that (cos(90^(@)-theta))/(1+sin(90^(@)-theta))+(1+sin(90^(@)-theta))/(cos(90^(@)-theta))=2cosec theta

If 1+sin theta=9cos theta and 0^(@)

Prove that:b. cos(90^@-theta)/(1+sin(90^@-theta))+(1+sin(90^@-theta))/cos(90^@-theta)=2cosectheta

Evaluate (sin (90 - theta). cos (90 - theta))/(sin theta cos theta)

What is the value of sin (180-theta)sin (90- theta)+[cot(90- theta)// 1+tan^2 theta] ? sin (180-theta)sin (90- theta)+[cot(90- theta)// 1+tan^2 theta] का मान क्या है?
