develop a code that determines the following sum for an value of x>0. The program calculates the sum by adding the terms and stopping when either, the value of a term is less than or equal to 0.0001, or the number of terms exceeds zero. If the value of the function is calculated successfully, it displays the value(sum) and the number of terms used. If the looping stops because the 30th term is not smaller than 0.001 the program displays a message indicating "more than 30 terms are needed."
sum(x^n/n!)=x/1!+x^2/2!+x^3+3!

‘...or the number of terms exceeds zero’
How do we interpret that?

The code depends on who gets the extra credit J
I would recommend using a while loop like another example in page 4 of Cleve Moler's book, http://www.mathworks.com/moler/zeros.pdf and keeping a running sum.
Goodluck!
