Hi everyone, I am trying to compute the normal distribution of a function. So I need to integrate from 'a' to 'b' and get a decimal answer that would be the probability. When I integrate I get erf; how do I convert to decimal?[image: Formula.png]
This is my code: import sympy as syms from sympy import exp,sqrt,pi a=195 b=205 x= syms.symbols('x') u=202 rho=4 f=syms.exp((-(x-u)**2)/(2*rho**2))/(rho*syms.sqrt(2*syms.pi)) Prob= syms.integrate(f,(x,a,b)) Prob.evalf -- You received this message because you are subscribed to the Google Groups "sympy" group.
