24. (3) ( frac{sin theta}{(1+cos theta)}+frac{(1+cos theta)}{sin theta} ) ( begin{aligned} &=frac{sin ^{2} theta+(1+cos theta)^{2}}{(1+cos theta)(sin theta)} =& frac{sin ^{2} theta+1+cos ^{2} theta+2 cos theta}{(1+cos theta)(sin theta)} =& frac{sin ^{2} theta+1+cos ^{2} theta+2 cos theta}{(1+cos theta)(sin theta)} =& frac{1+1+2 cos theta}{(1+cos theta)(sin theta)}=frac{2+2 cos theta}{(1+cos theta)(sin theta)} =& frac{2(1+cos theta)}{(1+cos theta)(sin theta)}=frac{2}{sin theta} end{aligned} )
