-2sqrt(2)cos(θ)=2

- 22 cos (θ) = 2

θ = \frac{3 π}{4} + 2 πn, θ = \frac{5 π}{4} + 2 πn

Solution steps

- 22 cos (θ) = 2

Divide both sides by

- 22

cos (θ) = - \frac{2}{2}

General solutions for

cos (θ) = - \frac{2}{2}

θ = \frac{3 π}{4} + 2 πn, θ = \frac{5 π}{4} + 2 πn

cos (θ) = \frac{6}{2}

x, - sin (0.6 (x + y)) \cdot 0.6 + 0.25 = 0

5 sin (60 t) = 0

18 sin^{2} (x) + 3 cos (x) - 17 = 0

sin (2 θ) = 0.4905
