 Author Comment/Response sunujoseph 05/19/06 05:49am hai , i have been trying hard for integrating a complicated function ..between the limits -infinity to + infinity.. using mathematica but in the result am getting a very complicated function with the error function..which am not at all able to solve.. my code is written in the following way.. f = x1[z] * Exp[(-(t - xc[z])^2)/(x2[z] ^2) + ( I x3[z]*(t - xc[z])^2 )/ 2 + I*xf[ z]*(t - xc[z]) + I x4[z]]; g = y1[z] * Exp[(-(t - yc[z])^2)/(y2[z] ^2) + ( I y3[z]*(t - yc[z])^2 )/ 2 + I*yf[z]*(t - yc[z]) + I y4[z]]; fx1c = D[f, x1[z]] /.\[InvisibleSpace]Complex[0, n_] -> -Complex[0, n]; F1 = κ*ComplexExpand[Re[g*fx1c*Exp[I*θ]]] Integrate[F1, {t, -∞, ∞}, Assumptions -> {y3[z] > x3[z], θ = 0}] i have attached the whole mathematica notebook.. please help me thanks in advance sunujoseph Attachment: errorfunction.nb, URL: ,
