Помогите решить алгебру 10 класс
[tex] \frac{2 \sin^{2} ( \alpha ) - 1}{1 - 2 \cos^{2} ( \alpha ) } + \tan^{2} ( \alpha ) [/tex]
[tex] \frac{ \sin^{2} (x) - \cos^{2} (x) + \cos^{4} (x) }{ \cos^{2} (x) - \sin ^{2} (x) + \sin^{4} (x) } [/tex]
[tex] \frac{ \sin^{2} (x) \cot^{2} (x) }{1 - \sin^{2} (x) } + \cot^{2} (x) [/tex]
[tex] \frac{ \cos^{2} ( \gamma ) - \cot^{2} ( \gamma ) + 1 }{ \sin^{2} ( \gamma ) + \tan^{2} ( \gamma ) - 1 } [/tex]
