Answer 2

The equation you provided is:

2x = ±arccos(-0.5) + 2πn

In this equation, 'x' is the variable, '±' represents both positive and negative solutions, 'arccos' is the inverse cosine function, 'n' is an integer, and 'π' is the mathematical constant pi.

To solve for 'x,' we can proceed as follows:

1. Solve for the principal value of arccos(-0.5): arccos(-0.5) ≈ 2.0944 radians or 120 degrees

2. Substitute the principal value into the equation: 2x = ±2.0944 + 2πn

3. Divide both sides by 2: x = ±1.0472 + πn

So the general solution for 'x' is: x = 1.0472 + πn or x = -1.0472 + πn

Here, 'n' can be any integer, and each value of 'n' will give a unique solution for 'x.'
