\frac{2 cos ( x )}{2} = \frac{- 0.2}{2}

Simplificar

\frac{2 cos ( x )}{2} = \frac{- 0.2}{2}

Simplificar

\frac{2 cos ( x )}{2} : cos (x)

\frac{2 cos ( x )}{2}

Dividir:

\frac{2}{2} = 1

= cos (x)

Simplificar

\frac{- 0.2}{2} : - 0.1

\frac{- 0.2}{2}

Aplicar las propiedades de las fracciones:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{0.2}{2}

Dividir:

\frac{0.2}{2} = 0.1

= - 0.1

cos (x) = - 0.1

cos (x) = - 0.1

cos (x) = - 0.1

Soluciones generales para

cos (x) = - 0.1

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

x = arccos (- 0.1) + 2 πn, x = - arccos (- 0.1) + 2 πn

x = arccos (- 0.1) + 2 πn, x = - arccos (- 0.1) + 2 πn
