" Find the value of "cos theta cos(90-theta)-sin theta sin(90-0)

Find the value of sin theta xxcos (90-theta) +cos thetaxx sin (90-theta) .

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

Write the value of sintheta cos(90^(@)-theta)+costheta sin(90^(@)-theta).

Evaluate cos thetasin theta + cos thetacos (90 - theta) + {(sin theta - sin (90 - theta)}^2 .

Find the value of (sin theta)/(cos (90^@+theta))+(sin theta)/(sin (180^@+theta))+(tan(90^@+theta))/(cot theta)

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

If sin theta = 12/13 (0^(@) lt theta lt 90^(@)) , find the value of (sin^(2) theta - cos^(2)theta)/(2 sin theta cos theta) xx (1)/(tan^(2)theta) .

If 5 sin theta-4 cos theta=0, 0^@ < theta<90^@ , then the value of (5sin theta-2 cos theta)/(5sin theta+3 cos theta) is:
