सिद्ध कीजिए कि :
`sin theta * cos (90^(@) - theta) + cos theta sin (90^(@) - theta) = 1`

sin theta cos (90^(@) - theta) + cos theta sin ( 90^(@)-0)= ________

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

Evaluate sin theta sec (90 - theta) + cos theta cosec (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))

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

Prove the following: sin theta sin(90^(@)-theta)-cos theta cos(90^(@)-theta)=0

Prove the following: sin theta sin(90^(@)-theta)-cos theta cos(90^(@)-theta)=0

sin(90^(@)-theta)costheta+cos(90^(@)-theta)sintheta= ………… .

((cos (90 ^ (@)) - theta) sin (90 ^ (@) - theta)) / (tan (90 ^ (@) - theta))

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