General solutions for

cos (x) = - 0.175

cos (x) = - a \Rightarrow x = arccos (- a) + 2 πn, x = - arccos (- a) + 2 πn

x = arccos (- 0.175) + 2 πn, x = - arccos (- 0.175) + 2 πn

x = arccos (- 0.175) + 2 πn, x = - arccos (- 0.175) + 2 πn

Show solutions in decimal form

x = 1.74670 \dots + 2 πn, x = - 1.74670 \dots + 2 πn

sec^{2} (x) = 2 tan^{2} (x)

\frac{sin ( x )}{cos ( x )} - 5 + \frac{4 cos ( x )}{sin ( x )} = 0

x, y = sin (3.2 x)

sin (x) = 0.37, π < x < \frac{π}{2}

5 cot (x) + 3 tan (x) = 8
