`cos theta sin (90^(@)-theta)+sin theta cos (90^(@)-theta)=1`

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

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))

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

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= ………… .

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

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

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