Error function wolfram
WebMar 31, 2016 · Wolfram Alpha gives an answer to this integral with some strange erf thing. Surely it is quite clear that there is an answer to this, and it is I = − 1 2 x e − x 2. This can be seen because d d x ( − 1 2 x e − x 2) = − 1 2 x ( − 2 x) e − x 2 = e − x 2 and by considering the fundamental theorem of calculus. calculus Share Cite Follow WebDec 21, 2014 · As a matter of fact, I have to use 'p' in other calculations. It means 'p' must be as a parameter not directly as a numeric. the final step is just an integration of a function of 'p' and 'a' (Which is absent here). Every thing is ok with 'p' and 'a'. But that Integration (containing functions of 'p' and 'a') will be gotten stuck.

WebJan 11, 2016 · I need an algorithm/approximation to compute the Scaled Complementary Error Function, erfcx (x) to double-float precision. I'm on a work PC so I’m limited to using Excel and VBA and I cannot use external libraries or add-ins: I need to code this myself. Excel only provides erf () and erfc () functions.
