sin theta cos(90^(@)-theta)+cos theta sin(90^(@)-theta)

Prove sin(180-theta)=sintheta

Prove that (cot(180^(@) + theta) sin (90^(@)-theta) cos(-theta))/(sin(270^(@) + theta) tan(-theta) "cosec"(360^(@) + theta)) = cos^(2)theta cot theta .

If tan theta = -(5)/(12) and theta is not in the fourth quadrant then ( tan (90^(@)+ theta ) - sin(180^(@) - theta ))/( sin (270^(@)- theta ) + " cosec " (360^(@) - theta ))=

Evaluate : sin theta cos theta - (sin theta cos (90^(@) - theta) cos theta)/( sec (90^(@) - theta)) - (cos theta sin (90^(@) - theta) sin theta)/( cosec (90^(@) - theta))

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

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