Webderivative of the error function - Wolfram Alpha derivative of the error function Natural Language Math Input Extended Keyboard Examples Have a question about using … WebThe value of erf(z) can be found in mathematical tables, as build-in functions in calculators and spread sheets. If you have a programmable calculator, you may find the following approximation useful (it is accurate to 1 part in 10 7): erf(z) = 1 - (a 1T + a 2T 2 +a 3T 3 +a 4T 4 +a 5T 5) e-z 2 where T = 1 1+P z and P = 0.3275911

WebAug 15, 2024 · A high (absolute) value for the derivative at a certain point means that the function is very steep, and a small change in input may result in a drastic change in its output; conversely, a low absolute value means little change, so not steep at all, with the extreme case that the function is constant when the derivative is zero. WebApr 23, 2016 · The error function erf ( x) is just 2 π ∫ 0 x e − t 2 d t, so its derivative is just 2 π e − x 2.
