Fullscreen

( frac{sin (90-theta) sec (180-theta) sin (-theta)}{sin (180+theta) cot left(360^{circ}-thetaright) operatorname{cosec}(90+theta)} )
( =frac{(cos theta)(+sec theta) cdot(+sin theta)}{(+sin theta)(+cot theta)(sec theta)} )
( =frac{cos theta}{cot theta} )
( =frac{cos theta}{sin theta} )
( =frac{cos theta sin theta}{sin theta} )
( =sin theta )
