In addition to Simon's response, if you just want to perform a numerical integral (instead of a symbolic one, from which you then try to extract a number), you can use: sage: numerical_integral(e^(-x^2), -3, 3) (1.7724146965190428, 1.9677756052594506e-14) It returns a pair of real numbers. The first is a numerical approximation to the value of the integral, and the second is an upper bound on the error of this approximation. Type sage: numerical_integral? to find out more about this.
