5=5+4cos(θ)

5 = 5 + 4 cos (θ)

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

Solution steps

5 = 5 + 4 cos (θ)

Switch sides

5 + 4 cos (θ) = 5

Subtract

5

from both sides

5 + 4 cos (θ) - 5 = 5 - 5

Simplify

4 cos (θ) = 0

Divide both sides by

4

cos (θ) = 0

General solutions for

cos (θ) = 0

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

cos (θ) = - 0.47

1 + tan^{2} (x) cos (x) = sec (x)

sec (θ) = \frac{6}{2}

sin^{2} (x) + cos^{2} (x) = sin (x) csc^{2} (x)

1.5 2 = 3 cos (x)
