Question

The central difference approximation of finite y' (x) is
​

Answer 1

Step-by-step explanation:

The central difference approximation is then f′(x)≈f(x+h)−f(x−h)2h. Suppose you have a discrete approximation, y, to a function, f(x), which is in principle continuous but for which you only have some selection of data points: yi=f(xi), where xi may or may not be equally spaced.
