4csc(x)+8=0

4 csc (x) + 8 = 0

x = \frac{7 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

Degrees

x = 21 0^{\circ} + 36 0^{\circ} n, x = 33 0^{\circ} + 36 0^{\circ} n

Solution steps

4 csc (x) + 8 = 0

Move

8

to the right side

4 csc (x) + 8 = 0

Subtract

8

from both sides

4 csc (x) + 8 - 8 = 0 - 8

Simplify

4 csc (x) = - 8

4 csc (x) = - 8

Divide both sides by

4

4 csc (x) = - 8

Divide both sides by

4

\frac{4 csc ( x )}{4} = \frac{- 8}{4}

Simplify

\frac{4 csc ( x )}{4} = \frac{- 8}{4}

Simplify

\frac{4 csc ( x )}{4} : csc (x)

\frac{4 csc ( x )}{4}

Divide the numbers:

\frac{4}{4} = 1

= csc (x)

Simplify

\frac{- 8}{4} : - 2

\frac{- 8}{4}

Apply the fraction rule:

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

= - \frac{8}{4}

Divide the numbers:

\frac{8}{4} = 2

= - 2

csc (x) = - 2

csc (x) = - 2

csc (x) = - 2

x = \frac{7 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

x = \frac{7 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

2 cos (2 θ) + 3 = 2

sin (\frac{3 π}{2} - 2 x) = sin (x)

α, sin (α) - sin (β) = cos (β) - cos (α)

- \frac{6}{7} = tan (t)

sin (2 x) = 3
