( begin{aligned} operatorname{cosec}^{2} theta=1+cot ^{2} theta &=1 / sqrt{3} quad, quad frac{1-cos ^{2} theta}{2-sin ^{2} theta}=3 / 5 frac{cos e^{2} theta=4 / 3}{sin ^{2} thetaleft(2 cos e^{2} theta-1right)} &=frac{operatorname{cosec}^{2} theta-cot theta}{2 cos e^{2} theta-1} &=frac{4 / 3-1 / 3}{2 times frac{4}{3}-1}=frac{1}{3}-1 frac{3}{5} end{aligned} )
