" 10.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))

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

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

Prove that :(sin theta cos(90^(0)-theta)cos theta)/(sin(90^(0)-theta))+(cos theta sin(90^(0)-theta)sin theta)/(cos(90^(@)-theta))=1csc^(2)(90^(@)-theta)-tan^(2)theta=cos^(2)(90^(@)-theta)+cos^(2)theta

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

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