`sin(90^circ+theta)` is

sin(90^circ+2theta) is

The value of sin(90^@-theta) is

Choose the correct option The value of sin theta cos (90- theta)+cos theta sin (90- theta) is

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

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

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

Find ‘x’ from the equation : cosec (90^@ -theta) - x sin (90^@- theta) tan (180^@+ theta) = sin (90^@+ theta) .

(sin(90^(@) -theta)sin theta)/(tan theta) + sin^(2) theta is equal to

Simplify the following : sin(90^@+ theta) tan (270^@ +theta) cot (90^@+theta) cosec (270^@+theta) .
