 \cos ^{2}  \alpha (1 +  \cot^{2} \alpha )

 \cos^{2} \alpha (1 +  \cos^{2} \alpha  \div  \sin^{2} \alpha )

 \cos^{2} \alpha ( (\sin^{2} \alpha+  \cos^{2} \alpha)  \div  \sin^{2} \alpha )

 \cos^{2} \alpha  \div \sin^{2} \alpha

\cot^{2} \alpha


vanshmadan: wrong
ayu856: then, what's right?
vanshmadan: answer is cot square theta + sin square theta cot square theta brother
vanshmadan: just use the reciprocal formulas of trigonometric ratios and terms
vanshmadan: best of luck
