Plz **How to Solve the Equation 2 cos(x) - 1 = 0 Using the Graph****Graph Explanation:**The graph depicts the cosine function \( y = \cos(x) \), shown as a smooth, wavy line fluctuating between -1 and 1. Two labeled intersections indicate that \( y = \frac{1}{2} \) serves as a horizontal line intersecting the cosine curve.Key points marked on the graph include:- \( x = \frac{\pi}{3} \)- \( x = \frac{5\pi}{3} \)- \( x = -\frac{\pi}{3} \)- \( x = -\frac{5\pi}{3} \)**Explanation and Solution Steps:**1. The equation \( 2 \cos(x) - 1 = 0 \) is equivalent to \( \cos(x) = \frac{1}{2} \).2. Intersection points of \( y = \cos(x) \) and \( y = \frac{1}{2} \) are the solutions we seek.3. Thus, the \( x \)-values corresponding to these intersections are the solutions to the equation.**Formulation:**- The equation \( \cos(x) = \frac{1}{2} \) gives the solution values for \( x \).- The solutions within the interval \((-2\pi, 2\pi)\) are \( x = -\frac{5\pi}{3}, -\frac{\pi}{3}, \frac{\pi}{3}, \frac{5\pi}{3} \).These solutions specify that the cosine curve intersects the horizontal line \( y = \frac{1}{2} \) at these points within the defined interval.
