Soluciones generales para

cos (1.57 x - π) = 0.428

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

1.57 x - π = arccos (0.428) + 2 πn, 1.57 x - π = 2 π - arccos (0.428) + 2 πn

1.57 x - π = arccos (0.428) + 2 πn, 1.57 x - π = 2 π - arccos (0.428) + 2 πn

Resolver

1.57 x - π = arccos (0.428) + 2 πn : x = \frac{arccos ( 0.428 )}{1.57} + \frac{2 πn}{1.57} + \frac{π}{1.57}
