\frac{π}{6} x = \frac{π}{6} + 2 πn, \frac{π}{6} x = \frac{5 π}{6} + 2 πn

\frac{π}{6} x = \frac{π}{6} + 2 πn, \frac{π}{6} x = \frac{5 π}{6} + 2 πn

Solve

\frac{π}{6} x = \frac{π}{6} + 2 πn : x = 1 + 12 n

\frac{π}{6} x = \frac{π}{6} + 2 πn

Multiply both sides by

6

\frac{π}{6} x = \frac{π}{6} + 2 πn

Multiply both sides by

6

= π

6 \cdot 2 πn = 12 πn

6 \cdot 2 πn

Multiply the numbers:

6 \cdot 2 = 12

= 12 πn

= π + 12 πn

π x = π + 12 πn

π x = π + 12 πn

π x = π + 12 πn

Divide both sides by

π

π x = π + 12 πn

Divide both sides by

π

\frac{π x}{π} = \frac{π}{π} + \frac{12 πn}{π}
