Error Function: Simple Definition, Table of Values

The error function, erf(x)=(2)/(√(π)) ∫0^x e^-t^2 d t important in probability and in the theories of heat flow and signal transmission, must be evaluated numerically because there is no elementary expression for the antiderivative of e^-t^2 a. Use Simpson's Rule with n=10 to estimate erf (1) b. In [0,1] |(d^4)/(d t^4)(e^-t)| ≤12 Give an upper bound for the magnitude of the error of the estimate in part (a). | Numerade

MathVibes on Instagram: "In complex analysis, the residue theorem, sometimes called Cauchy's residue theorem, is a powerful tool to evaluate line integrals of analytic functions over closed curves; it can often be used to compute real integrals and infinite series as well. It generalizes the Cauchy integral theorem and Cauchy's integral formula. The Residue Theorem is a powerful tool in complex analysis that simplifies evaluating complex line integrals over closed curves by relating the integral
