-2+cos(θ)=-2+6/5*cos(θ)

- 2 + cos (θ) = - 2 + \frac{6}{5} \cdot cos (θ)

θ = \frac{π}{2} + 2 πn, θ = \frac{3 π}{2} + 2 πn

Solution steps

- 2 + cos (θ) = - 2 + \frac{6}{5} cos (θ)

Solve by substitution

cos (θ) = 0

cos (θ) = 0 : θ = \frac{π}{2} + 2 πn, θ = \frac{3 π}{2} + 2 πn

Combine all the solutions

θ = \frac{π}{2} + 2 πn, θ = \frac{3 π}{2} + 2 πn

tan^{2} (y) + 3 - 2 sec^{2} (y) = 0

500 = 538.5 cos (x - 1 0^{\circ})

- 2 cos^{2} (x) = 3 (sin (x) - 1)

cos (x) tan (x) = sin (2 x)

2 ∣ sin (4 θ) ∣ = 0
