Create code that solves sum x^n/n!= x/1! + x^2/2! + x^3/3! + x^4/4! + .... for any value x>0. The function calculates the sum by adding the terms and stoping when the value of the term<=0.00001 or the number of terms exceeds 40.

function Summantion(x)
n=1;
Sum = 0;
while( n <= 40)
term = pow(x,n)/factorial(n);
if term <= 0.00001
break;
end
Sum = Sum + (x^n)/factorial(n);
n = n+1;
end
disp(['Sum = ' num2str(Sum)])
disp(['Terms = ' num2str(n)])

change pow(x,n) tp x^n. This should work now. In command window you should give the command Summantion(2).. whre x is 2
