\frac{π}{6} t = \frac{π}{2} + 2 πn, \frac{π}{6} t = \frac{3 π}{2} + 2 πn

\frac{π}{6} t = \frac{π}{2} + 2 πn, \frac{π}{6} t = \frac{3 π}{2} + 2 πn

Solve

\frac{π}{6} t = \frac{π}{2} + 2 πn : t = 3 + 12 n

\frac{π}{6} t = \frac{π}{2} + 2 πn

Multiply both sides by

6

\frac{π}{6} t = \frac{π}{2} + 2 πn

Multiply both sides by

6

6 \cdot \frac{π}{6} t = 6 \cdot \frac{π}{2} + 6 \cdot 2 πn

Simplify

6 \cdot \frac{π}{6} t = 6 \cdot \frac{π}{2} + 6 \cdot 2 πn

Simplify

6 \cdot \frac{π}{6} t : π t

6 \cdot \frac{π}{6} t

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{6 π}{6} t

Cancel the common factor:

6

= t π

Simplify

6 \cdot \frac{π}{2} + 6 \cdot 2 πn : 3 π + 12 πn

6 \cdot \frac{π}{2} + 6 \cdot 2 πn

6 \cdot \frac{π}{2} = 3 π

6 \cdot \frac{π}{2}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{π 6}{2}

Divide the numbers:

\frac{6}{2} = 3

= 3 π

6 \cdot 2 πn = 12 πn

6 \cdot 2 πn

Multiply the numbers:

6 \cdot 2 = 12

= 12 πn

= 3 π + 12 πn

π t = 3 π + 12 πn

π t = 3 π + 12 πn

π t = 3 π + 12 πn

Divide both sides by

π

π t = 3 π + 12 πn

Divide both sides by

π

\frac{π t}{π} = \frac{3 π}{π} + \frac{12 πn}{π}

Simplify

\frac{π t}{π} = \frac{3 π}{π} + \frac{12 πn}{π}

Simplify

\frac{π t}{π} : t

Divide the numbers:

\frac{18}{2} = 9

= 9 π

6 \cdot 2 πn = 12 πn

6 \cdot 2 πn

Multiply the numbers:

6 \cdot 2 = 12

= 12 πn

= 9 π + 12 πn

π t = 9 π + 12 πn

π t = 9 π + 12 πn

π t = 9 π + 12 πn

Divide both sides by

π

π t = 9 π + 12 πn

Divide both sides by

π

\frac{π t}{π} = \frac{9 π}{π} + \frac{12 πn}{π}
