'Sympy strange summation simplification
I had a long math expression involving
which I wanted to simplify using sympy. I received an output that I didn't quite get. It turned out that the problem appears when I want to simplify the above expression, so
from sympy import IndexedBase, Symbol, Sum, exp
x = IndexedBase('x')
i = Symbol('i', integer=True)
n = Symbol('n', integer=True)
t = Symbol('t', real=True)
(1/n*Sum(exp(t*x[i]), (i, 1, n))).simplify()
gives
What is c1, c2, c3? The expression can't be simplified so what's this output actually?
