Hi all,
I hope everyone is enjoying themselves!
I am trying to compute the Fourier series of a simple signal(1 Volt square
with freq of 1hz and 0.5T pulse width).
This is what I need help with:
1- How can I make sympy display the results of the sigma summation as :
Ao+An1+An2+An3... etc in
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:

This is my code:
import sympy as syms
from sympy
Thanks Kalevi,
Its sorted now

.integrate(V*syms.cos(w*n*t),(t,0,T/2))
Bn= (w/syms.pi)*syms.integrate(V*syms.sin(w*n*t),(t,0,T/2))
f= Ao/2 +syms.Sum(An*syms.cos(n*w*t),(n,1,5))+
syms.Sum(Bn*syms.sin(n*w*t),(n,1,5))
f
syms.plot(f,(t,0,2*T))

Oh no sorry, I used %matplotlib tk at the start and now it opens the graph
in separate window.(Google groups does not allow to edit messages )
But how to expand the summation series?

Thanks Davide!
It works now
