3=3-3cos(θ)

3 = 3 - 3 cos (θ)

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

Solution steps

3 = 3 - 3 cos (θ)

Switch sides

3 - 3 cos (θ) = 3

Subtract

3

from both sides

3 - 3 cos (θ) - 3 = 3 - 3

Simplify

- 3 cos (θ) = 0

Divide both sides by

- 3

cos (θ) = 0

General solutions for

cos (θ) = 0

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

a, tan (a) - tan (b) = 0

cos (x) = - cos (\frac{π}{7})

5 cos (x) - sin (x) = 1

tan (2 θ) = - 1.75

cos (x) = \frac{3}{2}, tan (x)
