0=2+cos(θ)

0 = 2 + cos (θ)

No Solution for θ \in R

Solution steps

0 = 2 + cos (θ)

Switch sides

2 + cos (θ) = 0

Move

2

to the right side

2 + cos (θ) = 0

Subtract

2

from both sides

2 + cos (θ) - 2 = 0 - 2

Simplify

cos (θ) = - 2

cos (θ) = - 2

- 1 \leq cos (x) \leq 1

No Solution for θ \in R

8 tan (\frac{x}{2}) + 8 cos (x) tan (\frac{x}{2}) = 1, 0^{\circ} < x < 36 0^{\circ}

cos (θ) = - \frac{4}{5}, tan (θ) < 0

16 sin^{2} (x) = 8

- 2 cot (x) = 0

cos (\frac{θ}{2}) = 0
