Question

The natural exponential function can be expressed by $e^x = \sum_{n=0}^{\infty} \frac{x^n}{n!}$ Determine $e^2$ by calculating the sum of the series for: n1 = 5, n2 = 15, and n3 = 25. For each sum create a vector in which the first element if 0, the increment is 1 and the last term is 5, 15 or 25. Then use element-by-element operations to create a vector with the elements $\frac{x^n}{n!}$. Finally use the MATLAB built-in function SUM to add the terms of the series. Compare the values obtained with the value of $e^2$ calculated by MATLAB.

Determine $e^2$ by calculating the sum of the series for:
n1 = 5, n2 = 15, and n3 = 25.
For each sum create a vector in which the first element if 0, the increment is 1
and the last term is 5, 15 or 25. Then use element-by-element operations to
create a vector with the elements $\frac{x^n}{n!}$. Finally use the MATLAB built-in function
SUM to add the terms of the series. Compare the values obtained with the value
of $e^2$ calculated by MATLAB.

The natural exponential function can be expressed by
e^x = ∑n=0^∞(x^n)/(n!)
Determine e^2 by calculating the sum of the series for:
n1 = 5, n2 = 15, and n3 = 25.
For each sum create a vector in which the first element if 0, the increment is 1
and the last term is 5, 15 or 25. Then use element-by-element operations to
create a vector with the elements (x^n)/(n!). Finally use the MATLAB built-in function
SUM to add the terms of the series. Compare the values obtained with the value
of e^2 calculated by MATLAB.
