If tan theta=-(5)/(12),theta is not in the second quadrant then show that (sec(360-theta)+tan(90+theta))/(-sec(270+theta)+cos ec(-theta))=(181)/(338)

Prove that sin (270^(@)-theta) sin (90^(@)-theta)-cos(270^(@)-theta) cos (90^(@)+theta)+1=0

tan theta+tan(90^(@)-theta)=sec theta xx sec(90^(@)-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 ))=

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

The value of [cos (270^(@) +theta)cos (90^(@) -theta)-sin (270^(@) -theta)cos theta) is-

The value of cos(270^(@)+theta)cos(90^(@)+theta)-sin(270^(@)-theta)cos theta is

The value of cos (270^(@) + theta) cos ( 90^(@) -theta) -sin (270^(@) - theta) cos theta is

The value of cos (270^(@) + theta) cos ( 90^(@) -theta) -sin (270^(@) - theta) cos theta is
