Question

Solve Trig equation
2cos0 = 1

Answer 1

θ = 60 degrees

If needed in radians:

θ = π/3

Explanation:

2cos(θ) = 1

We are solving for theta.

We can divide 2 on both sides.

2cos(θ) = 1

/2 /2

cos(θ) = 1/2

Now we can use Inverse of cosine to isolate theta.

θ
`= cos^-^1(1/2)`

θ = 60 degrees

If needed in radians:

θ = π/3
