General solutions for

cos (x) = - 0.6

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

x = arccos (- 0.6) + 2 πn, x = - arccos (- 0.6) + 2 πn

x = arccos (- 0.6) + 2 πn, x = - arccos (- 0.6) + 2 πn

Show solutions in decimal form

x = 2.21429 \dots + 2 πn, x = - 2.21429 \dots + 2 πn

cos (x) = - 0.9

2 cos (x) + 3 sin (x) = 0

sec (\frac{x}{5}) = 10
