Question

( frac{0,}{sin ^{2} theta}=frac{cos ^{2} theta+tan ^{2} theta-1}{operatorname{sen}} )
( =frac{cos ^{2} theta+frac{sin ^{2} theta}{cos ^{2} theta}-1}{sin ^{2} theta} )
( =frac{cos ^{4} theta+sin ^{2} theta-cos ^{2} theta}{cos ^{2} theta} )
( =frac{cos ^{4} theta+sin ^{2} theta-cos ^{2} theta}{sin ^{2} theta cos ^{2} theta} )
( =frac{cos ^{2} 4 theta}{sin ^{2} theta cos ^{2} theta}+frac{sin ^{2} theta}{sin ^{2} theta cos ^{2} theta}-frac{cos ^{2} theta}{sin ^{2} theta cos ^{2} theta} )
( cot ^{2} theta+frac{1}{cos ^{2} theta}-frac{1}{sin ^{2} theta} )
( cot ^{2} theta+sec ^{2} theta-cos u^{2} theta )
( =cot ^{2} theta+sec ^{2} theta-left(cot ^{2} theta+1right) )
( =cot ^{2} theta+sec ^{2} theta-cot ^{2} theta-1 )
( operatorname{lc} e^{2} theta-1 )
( =tan ^{2} theta )
