WebUsing higher-order Taylor series directly to approximate y(t n+1) is cumbersome, because it requires evaluating derivatives of f. Therefore, our approach will be to use evaluations of f at carefully chosen values of its arguments, tand y, in order to create an approximation that is just as accurate as a higher-order Taylor series expansion of y ...
