\frac{π}{2} x = 0 + 2 πn, \frac{π}{2} x = π + 2 πn

\frac{π}{2} x = 0 + 2 πn, \frac{π}{2} x = π + 2 πn

Solve

\frac{π}{2} x = 0 + 2 πn : x = 4 n

\frac{π}{2} x = 0 + 2 πn

0 + 2 πn = 2 πn

\frac{π}{2} x = 2 πn

Multiply both sides by

2

\frac{π}{2} x = 2 πn

Multiply both sides by

2

2 \cdot \frac{π}{2} x = 2 \cdot 2 πn

Simplify

π x = 4 πn

π x = 4 πn

Divide both sides by

π

π x = 4 πn

Divide both sides by

π

\frac{π x}{π} = \frac{4 πn}{π}

Simplify

x = 4 n

x = 4 n

Solve

\frac{π}{2} x = π + 2 πn : x = 2 + 4 n

\frac{π}{2} x = π + 2 πn

Multiply both sides by

2

\frac{π}{2} x = π + 2 πn

Multiply both sides by

2

2 \cdot \frac{π}{2} x = 2 π + 2 \cdot 2 πn

Simplify

π x = 2 π + 4 πn

π x = 2 π + 4 πn

Divide both sides by

π

π x = 2 π + 4 πn

Divide both sides by

π

\frac{π x}{π} = \frac{2 π}{π} + \frac{4 πn}{π}

Simplify

\frac{π x}{π} = \frac{2 π}{π} + \frac{4 πn}{π}

Simplify

\frac{π x}{π} : x

\frac{π x}{π}

Cancel the common factor:

π

= x

Simplify

\frac{2 π}{π} + \frac{4 πn}{π} : 2 + 4 n

\frac{2 π}{π} + \frac{4 πn}{π}

Cancel

\frac{2 π}{π} : 2

\frac{2 π}{π}

Cancel the common factor:

π

= 2

= 2 + \frac{4 πn}{π}

Cancel

\frac{4 πn}{π} : 4 n

\frac{4 πn}{π}

Cancel the common factor:

π

= 4 n

= 2 + 4 n

x = 2 + 4 n

x = 2 + 4 n

x = 2 + 4 n

x = 4 n, x = 2 + 4 n
