sin^3(x)+sin(x)=2sin^{22}(x)

Solution

sin^{3} (x) + sin (x) = 2 sin^{22} (x)

Solution

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

Degrees

x = 0^{\circ} + 36 0^{\circ} n, x = 18 0^{\circ} + 36 0^{\circ} n, x = 9 0^{\circ} + 36 0^{\circ} n

Solution steps

sin^{3} (x) + sin (x) = 2 sin^{22} (x)

Solve by substitution

sin^{3} (x) + sin (x) = 2 sin^{22} (x)

Let:

sin (x) = u

u^{3} + u = 2 u^{22}

u^{3} + u = 2 u^{22} : u = 0, u = 1

u^{3} + u = 2 u^{22}

Switch sides

2 u^{22} = u^{3} + u

Move

u

to the left side

2 u^{22} = u^{3} + u

Subtract

u

from both sides

2 u^{22} - u = u^{3} + u - u

Simplify

2 u^{22} - u = u^{3}

2 u^{22} - u = u^{3}

Move

u^{3}

to the left side

2 u^{22} - u = u^{3}

Subtract

u^{3}

from both sides

2 u^{22} - u - u^{3} = u^{3} - u^{3}

Simplify

2 u^{22} - u - u^{3} = 0

2 u^{22} - u - u^{3} = 0

Factor

2 u^{22} - u - u^{3} : u (u - 1) (2 u^{20} + 2 u^{19} + 2 u^{18} + 2 u^{17} + 2 u^{16} + 2 u^{15} + 2 u^{14} + 2 u^{13} + 2 u^{12} + 2 u^{11} + 2 u^{10} + 2 u^{9} + 2 u^{8} + 2 u^{7} + 2 u^{6} + 2 u^{5} + 2 u^{4} + 2 u^{3} + 2 u^{2} + u + 1)

2 u^{22} - u - u^{3}

Factor out common term

u : u (2 u^{21} - u^{2} - 1)

2 u^{22} - u^{3} - u

Apply exponent rule:

a^{b + c} = a^{b} a^{c}

u^{3} = u^{2} u

= 2 u^{21} u - u^{2} u - u

Factor out common term

u

= u (2 u^{21} - u^{2} - 1)

= u (2 u^{21} - u^{2} - 1)

Factor

2 u^{21} - u^{2} - 1 : (u - 1) (2 u^{20} + 2 u^{19} + 2 u^{18} + 2 u^{17} + 2 u^{16} + 2 u^{15} + 2 u^{14} + 2 u^{13} + 2 u^{12} + 2 u^{11} + 2 u^{10} + 2 u^{9} + 2 u^{8} + 2 u^{7} + 2 u^{6} + 2 u^{5} + 2 u^{4} + 2 u^{3} + 2 u^{2} + u + 1)

2 u^{21} - u^{2} - 1

Use the rational root theorem

a_{0} = 1, a_{n} = 2

The dividers of

a_{0} : 1,

The dividers of

a_{n} : 1, 2

Therefore, check the following rational numbers:

\pm \frac{1}{1 , 2}

\frac{1}{1}

is a root of the expression, so factor out

Therefore

\frac{2 u ^{5} - u ^{2} - 1}{u - 1} = 2 u^{4} + \frac{2 u ^{4} - u ^{2} - 1}{u - 1}

= 2 u^{20} + 2 u^{19} + 2 u^{18} + 2 u^{17} + 2 u^{16} + 2 u^{15} + 2 u^{14} + 2 u^{13} + 2 u^{12} + 2 u^{11} + 2 u^{10} + 2 u^{9} + 2 u^{8} + 2 u^{7} + 2 u^{6} + 2 u^{5} + 2 u^{4} + \frac{2 u ^{4} - u ^{2} - 1}{u - 1}

Divide

\frac{2 u ^{4} - u ^{2} - 1}{u - 1} : \frac{2 u ^{4} - u ^{2} - 1}{u - 1} = 2 u^{3} + \frac{2 u ^{3} - u ^{2} - 1}{u - 1}

Divide the leading coefficients of the numerator

2 u^{4} - u^{2} - 1

and the divisor

u - 1 : \frac{2 u ^{4}}{u} = 2 u^{3}

Quotient = 2 u^{3}

Multiply

2 u^{3} : 2 u^{4} - 2 u^{3}

Subtract

2 u^{4} - 2 u^{3}

from

2 u^{4} - u^{2} - 1

to get new remainder

Remainder = 2 u^{3} - u^{2} - 1

Therefore

\frac{2 u ^{4} - u ^{2} - 1}{u - 1} = 2 u^{3} + \frac{2 u ^{3} - u ^{2} - 1}{u - 1}

= 2 u^{20} + 2 u^{19} + 2 u^{18} + 2 u^{17} + 2 u^{16} + 2 u^{15} + 2 u^{14} + 2 u^{13} + 2 u^{12} + 2 u^{11} + 2 u^{10} + 2 u^{9} + 2 u^{8} + 2 u^{7} + 2 u^{6} + 2 u^{5} + 2 u^{4} + 2 u^{3} + \frac{2 u ^{3} - u ^{2} - 1}{u - 1}

Divide

\frac{2 u ^{3} - u ^{2} - 1}{u - 1} : \frac{2 u ^{3} - u ^{2} - 1}{u - 1} = 2 u^{2} + \frac{u ^{2} - 1}{u - 1}

Divide the leading coefficients of the numerator

2 u^{3} - u^{2} - 1

and the divisor

u - 1 : \frac{2 u ^{3}}{u} = 2 u^{2}

Quotient = 2 u^{2}

Multiply

2 u^{2} : 2 u^{3} - 2 u^{2}

Subtract

2 u^{3} - 2 u^{2}

from

2 u^{3} - u^{2} - 1

to get new remainder

Remainder = u^{2} - 1

Therefore

\frac{2 u ^{3} - u ^{2} - 1}{u - 1} = 2 u^{2} + \frac{u ^{2} - 1}{u - 1}

= 2 u^{20} + 2 u^{19} + 2 u^{18} + 2 u^{17} + 2 u^{16} + 2 u^{15} + 2 u^{14} + 2 u^{13} + 2 u^{12} + 2 u^{11} + 2 u^{10} + 2 u^{9} + 2 u^{8} + 2 u^{7} + 2 u^{6} + 2 u^{5} + 2 u^{4} + 2 u^{3} + 2 u^{2} + \frac{u ^{2} - 1}{u - 1}

Divide

\frac{u ^{2} - 1}{u - 1} : \frac{u ^{2} - 1}{u - 1} = u + \frac{u - 1}{u - 1}

Divide the leading coefficients of the numerator

u^{2} - 1

and the divisor

u - 1 : \frac{u ^{2}}{u} = u

Quotient = u

Multiply

u - 1

u : u^{2} - u

Subtract

u^{2} - u

from

u^{2} - 1

to get new remainder

Remainder = u - 1

Therefore

\frac{u ^{2} - 1}{u - 1} = u + \frac{u - 1}{u - 1}

= 2 u^{20} + 2 u^{19} + 2 u^{18} + 2 u^{17} + 2 u^{16} + 2 u^{15} + 2 u^{14} + 2 u^{13} + 2 u^{12} + 2 u^{11} + 2 u^{10} + 2 u^{9} + 2 u^{8} + 2 u^{7} + 2 u^{6} + 2 u^{5} + 2 u^{4} + 2 u^{3} + 2 u^{2} + u + \frac{u - 1}{u - 1}

Divide

\frac{u - 1}{u - 1} : \frac{u - 1}{u - 1} = 1

Divide the leading coefficients of the numerator

u - 1

and the divisor

u - 1 : \frac{u}{u} = 1

Quotient = 1

Multiply

u - 1

1 : u - 1

Subtract

u - 1

from

to get new remainder

Remainder = 0

Therefore

\frac{u - 1}{u - 1} = 1
