These include the telegrapher’s equation, studied by Lord Kelvin in connection with the Atlantic cable, and Kelvin’s estimate of the age of the earth (25 million years), based on the solution Hinzufügen Möchtest du dieses Video später noch einmal ansehen? C++: C++11 provides erf() and erfc() in the header cmath. Du kannst diese Einstellung unten ändern.

Derivative and integral[edit] The derivative of the error function follows immediately from its definition: d d z erf ⁡ ( z ) = 2 π e − z 2 . {\displaystyle LCCN64-60036. The integrand ƒ=exp(−z2) and ƒ=erf(z) are shown in the complex z-plane in figures 2 and 3. Inverse Error Function Hinzufügen Playlists werden geladen...

Watson, G.N. "Theorems Stated by Ramanujan (IV): Theorems on Approximate Integration and Summation of Series." J. Erf(1) Related functions[edit] The error function is essentially identical to the standard normal cumulative distribution function, denoted Φ, also named norm(x) by software languages, as they differ only by scaling and translation. Despite the name "imaginary error function", erfi ⁡ ( x ) {\displaystyle \operatorname ⁡ 8 (x)} is real when x is real. As it is necessary that the function should have a name, and as I do not know that any has been suggested, I propose to call it the Error-function, on account

H. The most reasonable expression I've found is that $$P(|N| < x) = \erf(x/\sqrt{2}).$$ This at least gets rid of all but one of the apparently spurious constants, but still has a Anmelden Teilen Mehr Melden Möchtest du dieses Video melden? http://imagextension.com/error-function/gaussian-error-function-ti-83.php Hints help you try the next step on your own.
