" 14."sin(90^(@)-theta)tan theta=sin theta

(sin(90^(@) -theta)sin theta)/(tan theta) + sin^(2) theta is equal to

If sin theta-cos theta=sqrt(2)sin(90^(@)-theta), then tan theta=

Simplify (sin(180^(@)+theta)cos(360^(@)-theta)tan(270^(@)-theta))/(sec^(2)(90^(@)+theta)tan(-theta)sin(270^(@)+theta))

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

(sin^(2) 20^(@) + sin^(2) 70^(@))/(cos^(2) 20^(@) + cos^(2) 70^(@)) + [ (sin (90^(@) - theta).sin theta)/(tan theta) + (cos (90^(@) - theta).cos theta)/(cot theta) ] .

Prove the following identities: cos theta sin(90o-theta)+sin theta cos(90o-theta)=1sin(sin(90o-theta))/(tan theta)-1=-sin^(2)theta( iii) (sin(90o-theta)cos(90o-theta))/(tan theta)=1-sin^(2)theta

Which of the following statement is true? (A) sin theta=cos (90-theta) (B) cos theta=tan (90-theta) (C) sin theta=tan(90-theta) (D) tan theta=tan (90-theta)

What is the simplified value of sin^(2) (90- theta) - [({sin(90-theta) sin theta})/(tan 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))
