Create a function with the following two expressions, then use one fplot command from the Command Window to plot them and make sure you add grids, title, xlabel and ylabel. Use the range [-20, 20]. y(1) = 5*sin(x)/x y(2) = 7 + 5*sin(2x)/x Evaluate the following integral numerically using MATLAB: a) integral^3_1 x * cos(x) dx b) integral^3_1 e^-x^3 dx
