Hi, 1. The problem statement, all variables and given/known data I am asked to evaluate the following sum S=Sigma(n=0 to N) x^n/n! (namely, e^x as n->Inf) for N=10:10:100 and x=10, so that every element S(i) is a partial sum which approximates function e^x with different accuracy. Below is my code, which doesn't work. 2. Relevant equations 3. The attempt at a solution x=10; N=10; i=0; while (N<=100), S(i)=double(symsum(x^n/sym('n!'), n, 0, N)); i=i+1; N=N+10; end Would anyone please tell me where I am going wrong and how it may be corrected? I'd appreciate some guidance.
