5 a = 0 + 2 πn, 5 a = π + 2 πn

5 a = 0 + 2 πn, 5 a = π + 2 πn

Solve

5 a = 0 + 2 πn : a = \frac{2 πn}{5}

5 a = 0 + 2 πn

0 + 2 πn = 2 πn

5 a = 2 πn

Divide both sides by

5

5 a = 2 πn

Divide both sides by

5

\frac{5 a}{5} = \frac{2 πn}{5}

Simplify

a = \frac{2 πn}{5}

a = \frac{2 πn}{5}

Solve

5 a = π + 2 πn : a = \frac{π}{5} + \frac{2 πn}{5}

5 a = π + 2 πn

Divide both sides by

5

5 a = π + 2 πn

Divide both sides by

5

\frac{5 a}{5} = \frac{π}{5} + \frac{2 πn}{5}

Simplify

a = \frac{π}{5} + \frac{2 πn}{5}

a = \frac{π}{5} + \frac{2 πn}{5}

a = \frac{2 πn}{5}, a = \frac{π}{5} + \frac{2 πn}{5}
