-pi/2 sin((pix)/2)=0

Solution

- \frac{π}{2} sin (\frac{π x}{2}) = 0

Solution

x = 4 n, x = 2 + 4 n

Degrees

x = 0^{\circ} + 229.18311 \dots^{\circ} n, x = 114.59155 \dots^{\circ} + 229.18311 \dots^{\circ} n

Solution steps

- \frac{π}{2} sin (\frac{π x}{2}) = 0

Multiply both sides by

2

- \frac{π}{2} sin (\frac{π x}{2}) = 0

Multiply both sides by

2

2 (- \frac{π}{2} sin (\frac{π x}{2})) = 0 \cdot 2

Simplify

- π sin (\frac{π x}{2}) = 0

- π sin (\frac{π x}{2}) = 0

Divide both sides by

- π

- π sin (\frac{π x}{2}) = 0

Divide both sides by

- π

\frac{- π sin ( \frac{π x}{2} )}{- π} = \frac{0}{- π}

Simplify

sin (\frac{π x}{2}) = 0

sin (\frac{π x}{2}) = 0

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

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

Solve

\frac{π x}{2} = 0 + 2 πn : x = 4 n

\frac{π x}{2} = 0 + 2 πn

0 + 2 πn = 2 πn

\frac{π x}{2} = 2 πn

Multiply both sides by

2

\frac{π x}{2} = 2 πn

Multiply both sides by

2

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

\frac{π x}{2} = π + 2 πn

Multiply both sides by

2

\frac{π x}{2} = π + 2 πn

Multiply both sides by

2

\frac{2 π x}{2} = 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:

Cancel

\frac{2 π}{π} : 2

\frac{2 π}{π}

Cancel the common factor:

π

= 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
