-3-2cos(θ)=2

- 3 - 2 cos (θ) = 2

No Solution for θ \in R

Solution steps

- 3 - 2 cos (θ) = 2

Move

3

to the right side

- 3 - 2 cos (θ) = 2

Add

3

to both sides

- 3 - 2 cos (θ) + 3 = 2 + 3

Simplify

- 2 cos (θ) = 5

- 2 cos (θ) = 5

Divide both sides by

- 2

- 2 cos (θ) = 5

Divide both sides by

- 2

\frac{- 2 cos ( θ )}{- 2} = \frac{5}{- 2}

Simplify

cos (θ) = - \frac{5}{2}

cos (θ) = - \frac{5}{2}

- 1 \leq cos (x) \leq 1

No Solution for θ \in R

4 sec (θ) = - 5 - tan^{2} (θ)

- 15 + 4 cos (θ) = - 15 - 22

cos (2 x) = 1 - 3 sin (x)

3 sin^{2} (x) - 7 sin (x) - 2 = 0

3 sin (2 t) + 4 = 1, - \frac{π}{2} \leq t \leq \frac{π}{2}
