-1 0 1 \sin t \cos t \tg t \ctg t \sin^2 t \cos^2 t \tg^2 t \ctg^2 t

\textcolor{white}{\boxed{\textcolor{black}{\dfrac{1+\tg^2 t}{1+\ctg^2 t}}}}=

\textcolor{white}{\boxed{\textcolor{black}{\dfrac{\sin^2 t}{1-\cos t}- \sin^2 t - \cos^2 t}}}=

\textcolor{white}{\boxed{\textcolor{black}{\dfrac{\sin^2 t + \cos^2 t}{\tg^2 t \cdot \cos^2 t}-\dfrac{\cos^2 t}{1-\cos^2 t}}}}=
