4sin(b)+sqrt(8)=0

Solution

4 sin (b) + 8 = 0

Solution

b = \frac{5 π}{4} + 2 πn, b = \frac{7 π}{4} + 2 πn

Degrees

b = 22 5^{\circ} + 36 0^{\circ} n, b = 31 5^{\circ} + 36 0^{\circ} n

Solution steps

4 sin (b) + 8 = 0

Simplify

4 sin (b) + 8 : 4 sin (b) + 22

4 sin (b) + 8

8 = 22

8

Prime factorization of

8 : 2^{3}

8

8

divides by

28 = 4 \cdot 2

= 2 \cdot 4

4

divides by

24 = 2 \cdot 2

= 2 \cdot 2 \cdot 2

2

is a prime number, therefore no further factorization is possible

= 2 \cdot 2 \cdot 2

= 2^{3}

= 2^{3}

Apply exponent rule:

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

= 2^{2} \cdot 2

Apply radical rule:

= 2 2^{2}

Apply radical rule:

2^{2} = 2

= 22

= 4 sin (b) + 22

4 sin (b) + 22 = 0

Move

22

to the right side

4 sin (b) + 22 = 0

Subtract

22

from both sides

4 sin (b) + 22 - 22 = 0 - 22

Simplify

4 sin (b) = - 22

4 sin (b) = - 22

Divide both sides by

4

4 sin (b) = - 22

Divide both sides by

4

\frac{4 sin ( b )}{4} = \frac{- 2 2}{4}

Simplify

\frac{4 sin ( b )}{4} = \frac{- 2 2}{4}

Simplify

\frac{4 sin ( b )}{4} : sin (b)

\frac{4 sin ( b )}{4}

Divide the numbers:

\frac{4}{4} = 1

= sin (b)

Simplify

\frac{- 2 2}{4} : - \frac{2}{2}

\frac{- 2 2}{4}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{2 2}{4}

Cancel the common factor:

2

= - \frac{2}{2}

sin (b) = - \frac{2}{2}

sin (b) = - \frac{2}{2}

sin (b) = - \frac{2}{2}
