0=sin(pix)

0 = sin (π x)

x = 2 n, x = 1 + 2 n

Degrees

x = 0^{\circ} + 114.59155 \dots^{\circ} n, x = 57.29577 \dots^{\circ} + 114.59155 \dots^{\circ} n

Solution steps

0 = sin (π x)

Switch sides

sin (π x) = 0

General solutions for

π x = 0 + 2 πn, π x = π + 2 πn

π x = 0 + 2 πn, π x = π + 2 πn

Solve

π x = 0 + 2 πn : x = 2 n

π x = 0 + 2 πn

0 + 2 πn = 2 πn

π x = 2 πn

Divide both sides by

π

π x = 2 πn

Divide both sides by

π

\frac{π x}{π} = \frac{2 πn}{π}

Simplify

x = 2 n

x = 2 n

Solve

π x = π + 2 πn : x = 1 + 2 n

π x = π + 2 πn

Divide both sides by

π

π x = π + 2 πn

Divide both sides by

π

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

Simplify

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

Simplify

\frac{π x}{π} : x

\frac{π x}{π}

Cancel the common factor:

π

= x

Simplify

\frac{π}{π} + \frac{2 πn}{π} : 1 + 2 n

\frac{π}{π} + \frac{2 πn}{π}

Apply rule

\frac{a}{a} = 1

\frac{π}{π} = 1

= 1 + \frac{2 πn}{π}

Cancel

\frac{2 πn}{π} : 2 n

\frac{2 πn}{π}

Cancel the common factor:

π

= 2 n

= 1 + 2 n

x = 1 + 2 n

x = 1 + 2 n

x = 1 + 2 n

x = 2 n, x = 1 + 2 n
