- Derivative

Numerical derivative of a function approaches the analytical or exact value as the two points on the function approach each other, that is, h approaches zero. Move either point A or point B and compare both the analytical (exact) and the numerical values of the derivative of the function. In the Input box change the function to f(x)=0.1*x^2 + x -1 to observe the effect.
