सिद्ध कीजिये कि `(costheta)/(sec(90^@ - theta) + 1) + (sin (90^@ - theta))/ (cosectheta -1) = 2 cot(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))

(cos(90^@+theta)sec(-theta)tan(180^@-theta))/(sin(360^@+theta)sec(180^@+theta)cot(90^@-theta))=

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

Prove that:b. cos(90^@-theta)/(1+sin(90^@-theta))+(1+sin(90^@-theta))/cos(90^@-theta)=2cosectheta

The value of (cos(90^@ - theta)sec(90^@ - theta) tan theta)/(cosec(90^@ - theta)sin(90^@ - theta)cot(90^@ - theta) (tan(90^@ - theta))/(cot theta) is____

What is the value of [tan^2 (90 - theta) - sin^2 (90 - theta)] cosec^2 (90 - theta) cot^2 (90 - theta) ?

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

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

If xsin(90^@-theta)cot(90^@-theta)=cos(90^@-theta) , then x=
