2 x = arctan (- \frac{5}{16}) + πn

Resolver

2 x = arctan (- \frac{5}{16}) + πn : x = - \frac{arctan ( \frac{5}{16} )}{2} + \frac{πn}{2}

x = - \frac{arctan ( \frac{5}{16} )}{2} + \frac{πn}{2}

15 sin^{2} (x) - 22 sin (x) + 8 = 0

1.333 \cdot sin (4 8^{\circ}) = sin (x)

x, y = cos (x^{2})

2 sin (θ) = 2 + 2 cos (θ)

tan (x) = \frac{1.3823}{10.1}
