3sqrt(3)sec(θ)+4=-2

33 sec (θ) + 4 = - 2

θ = \frac{5 π}{6} + 2 πn, θ = \frac{7 π}{6} + 2 πn

Degrees

θ = 15 0^{\circ} + 36 0^{\circ} n, θ = 21 0^{\circ} + 36 0^{\circ} n

Solution steps

33 sec (θ) + 4 = - 2

Move

4

to the right side

33 sec (θ) + 4 = - 2

Subtract

4

from both sides

33 sec (θ) + 4 - 4 = - 2 - 4

Simplify

33 sec (θ) = - 6

33 sec (θ) = - 6

Divide both sides by

33

33 sec (θ) = - 6

Divide both sides by

33

\frac{3 3 sec ( θ )}{3 3} = \frac{- 6}{3 3}

Simplify

\frac{3 3 sec ( θ )}{3 3} = \frac{- 6}{3 3}

Simplify

\frac{3 3 sec ( θ )}{3 3} : sec (θ)

\frac{3 3 sec ( θ )}{3 3}

Divide the numbers:

\frac{3}{3} = 1

= \frac{3 sec ( θ )}{3}

Cancel the common factor:

3

= sec (θ)

Simplify

\frac{- 6}{3 3} : - \frac{2 3}{3}

\frac{- 6}{3 3}

Apply the fraction rule:

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

= - \frac{6}{3 3}

Divide the numbers:

\frac{6}{3} = 2

= - \frac{2}{3}

Rationalize

- \frac{2}{3} : - \frac{2 3}{3}

- \frac{2}{3}

Multiply by the conjugate

\frac{3}{3}

= - \frac{2 3}{3 3}

33 = 3

33

Apply radical rule:

a a = a

33 = 3

= 3

= - \frac{2 3}{3}

= - \frac{2 3}{3}

sec (θ) = - \frac{2 3}{3}

sec (θ) = - \frac{2 3}{3}

sec (θ) = - \frac{2 3}{3}

θ = \frac{5 π}{6} + 2 πn, θ = \frac{7 π}{6} + 2 πn

θ = \frac{5 π}{6} + 2 πn, θ = \frac{7 π}{6} + 2 πn

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

3 sin (2 θ) = 2 cos (2 θ)

cos (x) + cos^{2} (x) = 0

cos (θ) = cos (1)

tan (\frac{x}{2}) = \pm \frac{1 - cos ( x )}{1 + cos ( x )}
