WebOct 13, 2009 · I think your rule of thumb assumes you use a first-order rule to approximate the derivative. However, the central difference rule you mention is second order, and the corresponding rule of thumb is h = EPSILON^ (1/3) which is approximately 10^ (-5) when using double precision. – Jitse Niesen Oct 13, 2009 at 13:05 WebA derivative is a function which measures the slope. x in some way, and is found by differentiating a function of the form y = f (x). When x is substituted into the derivative, the result is the slopeof the original function y = f (x). There are many different ways to indicate the operation of differentiation,
WebThe derivative of a function is the rate of change of the function's output relative to its input value. Given y = f (x), the derivative of f (x), denoted f' (x) (or df (x)/dx), is defined by the … WebBy the definition of a derivative this is the limit as h goes to 0 of: (g (x+h) - g (x))/h = (2f (x+h) - 2f (x))/h = 2 (f (x+h) - f (x))/h Now remember that we can take a constant multiple out of …
