\frac{3 cos ( a )}{3} = \frac{1}{3}

Simplificar

cos (a) = \frac{1}{3}

cos (a) = \frac{1}{3}

Aplicar propiedades trigonométricas inversas

cos (a) = \frac{1}{3}

Soluciones generales para

cos (a) = \frac{1}{3}

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

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

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