Recall that the command diff(f(x),x) symbolically finds the derivative of the function f. Recall also that the derivative is itself a function which can also be differentiated, giving us the second derivative of f, and so on. MATLAB will easily compute higher order derivatives using the command diff(f(x),x,n) Where n represents which derivative you want. Later, it will be very useful to find patterns in higher order derivatives. Ordinarily, this is most easily done by NOT simplifying the resulting expression,...
