0.5 x = 0 + 2 πn, 0.5 x = π + 2 πn

0.5 x = 0 + 2 πn, 0.5 x = π + 2 πn

Resolver

0.5 x = 0 + 2 πn : x = 4 πn

0.5 x = 0 + 2 πn

0 + 2 πn = 2 πn

0.5 x = 2 πn

Multiplicar ambos os lados por

10

0.5 x = 2 πn

To eliminate decimal points, multiply by 10 for every digit after the decimal pointThere is one digit to the right of the decimal point, therefore multiply by

10

0.5 x \cdot 10 = 2 πn \cdot 10

Simplificar

5 x = 20 πn

5 x = 20 πn

Dividir ambos os lados por

5

5 x = 20 πn

Dividir ambos os lados por

5

\frac{5 x}{5} = \frac{20 πn}{5}

Simplificar

x = 4 πn

x = 4 πn

Resolver

0.5 x = π + 2 πn : x = 2 π + 4 πn

0.5 x = π + 2 πn

Multiplicar ambos os lados por

10

0.5 x = π + 2 πn

To eliminate decimal points, multiply by 10 for every digit after the decimal pointThere is one digit to the right of the decimal point, therefore multiply by

10

0.5 x \cdot 10 = π 10 + 2 πn \cdot 10

Simplificar

5 x = 10 π + 20 πn

5 x = 10 π + 20 πn

Dividir ambos os lados por

5

5 x = 10 π + 20 πn

Dividir ambos os lados por

5

\frac{5 x}{5} = \frac{10 π}{5} + \frac{20 πn}{5}

Simplificar

\frac{5 x}{5} = \frac{10 π}{5} + \frac{20 πn}{5}

Simplificar

\frac{5 x}{5} : x

\frac{5 x}{5}

Dividir:

\frac{5}{5} = 1

= x

Simplificar

\frac{10 π}{5} + \frac{20 πn}{5} : 2 π + 4 πn

\frac{10 π}{5} + \frac{20 πn}{5}

Dividir:

\frac{10}{5} = 2

= 2 π + \frac{20 πn}{5}

Dividir:

\frac{20}{5} = 4

= 2 π + 4 πn

x = 2 π + 4 πn

x = 2 π + 4 πn

x = 2 π + 4 πn

x = 4 πn, x = 2 π + 4 πn
