Question

Solve cos theta=- sqrt (3)/2 on [0, 2pi) Write the first solution or lowest on [0, 2pi) . Round to the nearest hundredth .

Answer 1

2.62 radians

Explanation:

The angle is found from its cosine using the inverse cosine function.

cos(θ) = (-√3)/2

θ = arccos((-√3)/2) = 5π/6 ≈ 2.62 . . . radians
