Find all solutions of this equation in the interval [0, 2?):2 cos(x) + 1 = 0

Find all solutions of this equation in the interval [0, 2m) : 2cos(x) 4 1 Give your answers in radians. Do not use decimal approximations. Use 'pi'to represent m. Use commas to separate your answers. Remember that because trigonometric functions are periodic, they can have an infinite number of solutions to a given equation. In this problem, you are being asked to provide only those solutions that occur between O and 2m You can think of it like this: (0, 27T) defines our unit circle, and selecting a value for sine or cosine defines either a horizontal or vertical line to pass through our unit circle. As long as that line is not tangent to our unit circle, then it will intersect the circle twice. Each intersection gives us a point, and those two points each correspond to an angle between 0 and 2m
