`costheta/sin(90^@+theta)+sin(-theta)/sin(180^@+theta)-tan(90^@+theta)/cottheta`

Prove that (cos theta)/(sin(90^(@)+theta))+(sin(-theta))/(sin(180^(@)+theta))-(tan(90^(@)+theta))/(cot(theta))=3

Find the value of (sin theta)/(cos (90^@+theta))+(sin theta)/(sin (180^@+theta))+(tan(90^@+theta))/(cot theta)

Simplify (sin(270^@+theta)costheta+sin(270^@-theta)sintheta)/(sin(180^@-theta)costheta+sin(270^@-theta)cos(540^@+theta))

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

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 (90^@-theta) sec (180^@-theta)sin(-theta))/(sin (180^@+theta) cot (360^@-theta) "cosec"(90^@-theta)) ?

What is the value of : (sin(90^(@)-theta)sec(180^(@)-theta)sin(-theta))/(sin(180^(@)+theta)cot(360^(@)-theta)"cosec "(90^(@)+theta)) :

(sin(90^(@)-theta)sec(180^(@)-theta)sin(-theta))/(sin(180^(@)+theta)cot(360^(@)-theta)"cosec"(90^(@)+theta)) .

What is the value of , (sin(90^@-theta)sec(180^@-theta)sin(-theta))/(sin(180^@+theta)cot(360^@-theta)cosec(90^@+theta)) :

Prove that (cot(180^(@) + theta) sin (90^(@)-theta) cos(-theta))/(sin(270^(@) + theta) tan(-theta) "cosec"(360^(@) + theta)) = cos^(2)theta cot theta .
