What is the value of : (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 the following: sin theta sin(90^(@)-theta)-cos theta cos(90^(@)-theta)=0

Prove the following: sin theta sin(90^(@)-theta)-cos theta cos(90^(@)-theta)=0

The value of sin^(2) (90^(@) - theta) [ 1 + cot ^(2) (90^(@) - theta)] is

(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) ] .

What is the value of [sin (90^@-10 theta) -cos (pi- 6 theta)]//[cos (pi//2 -10 theta) - sin (pi- 6 theta)] ? [sin (90^@-10 theta) -cos (pi- 6 theta)]//[cos (pi//2 -10 theta) - sin (pi- 6 theta)] का मान क्या है?
