Webx and x + h, the approximation (5.1) is called a forward diﬀerencing or one-sided diﬀerencing. The approximation of the derivative at x that is based on the values of the function at x−h and x, i.e., f0(x) ≈ f(x)−f(x−h) h, is called a backward diﬀerencing (which is obviously also a one-sided diﬀerencing formula). http://mathforcollege.com/nm/simulations/mws/02dif/mws_dif_sim_comparedif.pdf
