Soluciones generales para

cos (\frac{π}{3} t) = \frac{1}{7}

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

\frac{π}{3} t = arccos (\frac{1}{7}) + 2 πn, \frac{π}{3} t = 2 π - arccos (\frac{1}{7}) + 2 πn

\frac{π}{3} t = arccos (\frac{1}{7}) + 2 πn, \frac{π}{3} t = 2 π - arccos (\frac{1}{7}) + 2 πn

Resolver

\frac{π}{3} t = arccos (\frac{1}{7}) + 2 πn : t = \frac{3 arccos ( \frac{1}{7} )}{π} + 6 n

\frac{π}{3} t = arccos (\frac{1}{7}) + 2 πn
