O Figure 1 Figure 1 shows a plot of part of the curve with equation y = cos x where x is measured in radians. Diagram 1, on the opposite page, is a copy of Figure 1. (a) Use Diagram 1 to show why the equation cos x - 2x - 1/2 = 0 has only one real root, giving a reason for your answer. Given that the root of the equation is a, and that a is small, (b) use the small angle approximation for cosx to estimate the value of a to 3 decimal places. (2)
