Let f: R→ R given by f(x) = 2 sin(x) - x² + 1. (a) Find an interval [a, b] for which f is continuous in [a, b] and f(a) and f(b) have opposite signs. (b) Prove that the equation 2 sin(x) = x² - 1 has at least one solution in (a, b). (c) Find this solution correct to three decimal places, using either the Newton-Raphson method, or a suitable iterative formula.
