Erika, it is very poor online etiquette to delete your question after there have been comments and answers posted. This is a disservice to the Answers community.

format long
I = 0.0;
Iexact = 0.904524237900272;
eps = 1e-15;
n = 0;
while abs(I-Iexact) > eps
I = I + (-1)^n/(factorial(2*n)*(4*n+1))
n = n+1;
end
n-1
I
