सिद्ध कीजिए कि `(cos theta)/(sin (90^(@) - theta) )+ (sin theta)/(cos (90^(@) - theta)) = 2`

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))

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

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

Prove that (cos(90^(@)-theta))/(1+sin(90^(@)-theta))+(1+sin(90^(@)-theta))/(cos(90^(@)-theta))=2cosec theta

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

Simplify : (cos(-theta))/(sin (90^(@)+theta))

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

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

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