Answer 2

Solving cos(x) + 2 = 0

To solve the equation cos(x) + 2 = 0, we can use the properties of trigonometric functions to find the values of x that satisfy the equation.

The equation cos(x) + 2 = 0 can be rewritten as cos(x) = -2. However, the cosine function has a range of -1 to 1, so there are no real solutions for x in this case.

Therefore, the equation cos(x) + 2 = 0 has no real solutions.
