`cot (90^(@) + theta) –cos (180^(@) + theta) + tan (360^(@) - theta) =0`

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

If tan theta = -(5)/(12) and theta is not in the fourth quadrant then ( tan (90^(@)+ theta ) - sin(180^(@) - theta ))/( sin (270^(@)- theta ) + " cosec " (360^(@) - theta ))=

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

If 0^(@)lt theta lt 90^(@) and cos theta=(4)/(5) find the values of tan(360^(@)-theta)

Solve (0^(@) le theta le 360^(@)) : (iii) tan theta + cot theta = 2 "sec" theta

Simplify the following : (cos (360^@-theta) cosec (180^@+ theta) cot (90^@-theta))/(sec (90^@+theta)cos (-theta)) .

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

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

Prove that: (cos ec(90^(@)+theta)+cot(450^(@)+theta))/(cos ec(90^(@)-theta)+tan(180^(@)-theta))+(tan(180^(@)+theta)+sec(180^(@)-theta))/(tan(360^(@)+theta)-sec(-theta))=2
