-4pi^2sin(2pix)=0

Solution

- 4 π^{2} sin (2 π x) = 0

Solution

x = n, x = \frac{1}{2} + n

Degrees

x = 0^{\circ}, x = 28.64788 \dots^{\circ}

Solution steps

- 4 π^{2} sin (2 π x) = 0

Divide both sides by

- 4 π^{2}

- 4 π^{2} sin (2 π x) = 0

Divide both sides by

- 4 π^{2}

\frac{- 4 π ^{2} sin ( 2 π x )}{- 4 π ^{2}} = \frac{0}{- 4 π ^{2}}

Simplify

sin (2 π x) = 0

sin (2 π x) = 0

2 π x = 0 + 2 πn, 2 π x = π + 2 πn

2 π x = 0 + 2 πn, 2 π x = π + 2 πn

Solve

2 π x = 0 + 2 πn : x = n

2 π x = 0 + 2 πn

0 + 2 πn = 2 πn

2 π x = 2 πn

Divide both sides by

2 π

2 π x = 2 πn

Divide both sides by

2 π

\frac{2 π x}{2 π} = \frac{2 πn}{2 π}

Simplify

\frac{2 π x}{2 π} = \frac{2 πn}{2 π}

Simplify

\frac{2 π x}{2 π} : x

\frac{2 π x}{2 π}

Divide the numbers:

\frac{2}{2} = 1

= \frac{π x}{π}

Cancel the common factor:

π

= x

Simplify

\frac{2 πn}{2 π} : n

\frac{2 πn}{2 π}

Divide the numbers:

\frac{2}{2} = 1

= \frac{πn}{π}

Cancel the common factor:

π

= n

x = n

x = n

x = n

Solve

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

2 π x = π + 2 πn

Divide both sides by

2 π

2 π x = π + 2 πn

Divide both sides by

2 π

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

Simplify

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

Simplify

\frac{2 π x}{2 π} : x

\frac{2 π x}{2 π}

Divide the numbers:

\frac{2}{2} = 1

= \frac{π x}{π}

Cancel the common factor:

π

= x

Simplify

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

\frac{π}{2 π} + \frac{2 πn}{2 π}

Cancel

\frac{π}{2 π} : \frac{1}{2}

\frac{π}{2 π}

Cancel the common factor:

π

= \frac{1}{2}

= \frac{1}{2} + \frac{2 πn}{2 π}

Cancel

\frac{2 πn}{2 π} : n

\frac{2 πn}{2 π}

Cancel

\frac{2 πn}{2 π} : n

\frac{2 πn}{2 π}

Divide the numbers:

\frac{2}{2} = 1

= \frac{πn}{π}

Cancel the common factor:

π

= n

= n

= \frac{1}{2} + n

x = \frac{1}{2} + n

x = \frac{1}{2} + n

x = \frac{1}{2} + n

x = n, x = \frac{1}{2} + n
