Answer

Explanation:

Step1: Use graphing - calculator

Graph the function (y = x^{2}+2\sin x - x^{3}-3\cos x) on the interval ([0, 2\pi)).

Step2: Find x - intercepts

The x - values of the points where the graph of (y = x^{2}+2\sin x - x^{3}-3\cos x) intersects the x - axis are the solutions of the equation (x^{2}+2\sin x - x^{3}-3\cos x = 0).
