Solutions générales pour

tan (x) = \frac{tan ^{2} ( b ) + 1}{csc ^{2} ( b )}

tan (x) = a \Rightarrow x = arctan (a) + πn

x = arctan (\frac{tan ^{2} ( b ) + 1}{csc ^{2} ( b )}) + πn

x = arctan (\frac{tan ^{2} ( b ) + 1}{csc ^{2} ( b )}) + πn

sin (x) + sin^{2} (\frac{x}{2}) = \frac{1}{2}

sin^{5} (x) + sin^{3} (x) = 0

5 sin^{2} (x) cos (7 x) - cos (7 x) = 0

so l v e f or x, cos^{2} (x) \cdot z^{2} - 2 cos^{2} (x) \cdot z + 1 = 0

sin (a) + sin (12 0^{\circ} + a) + sin (12 0^{\circ} - a) = 0
