I need help with Euler's number

Question 1

The Euler's number (e) is an important mathematical constant that forms the base of the natural logarithms. This number can be obtained in MATLAB by typing: exp(1), in other words, e to the power of 1. The exact value of e can be defined by the infinite series:

where n! is the factorial of n.

You are asked to create a MATLAB M-file named “question1.m” (exactly like this, without capital letters or spaces) that

1. uses a for loop to display in the Command Window the first 10 terms in the sequence. Hint:the factorial of n (or n!) in MATLAB is obtained by typing factorial(n).
2. calculates the series using the first 10 terms.
3. obtains the error of the previous series (in %) with respect to the value of e that is stored in the memory of MATLAB.
4. creates a plot in which the number of terms that are included in the series appears in the abscissa (x) and the result of the series for the corresponding number of terms appears in the ordinate (y). The line should contain ‘x’ markers to indicate each value of the series.
5. includes in the plot useful labels and a line at y = e to represent the value to which the series should converge.

What have you done so far? What specific problems are you having with your code?

Where can I find the answer in the above question?

Romario - why not trying to code this yourself? The question seems fairly clear on what needs to be done.
