Example of Exponential function modular program:

In order to view the distinction in the approximate value for e as n increases, the user kept choosing Limit & entering larger and larger values each time in the illustration below:

>> eapplication

Enter a positive integer for n: 4

An approximation of e with n = 4 is 2.44

Enter a positive integer for n: 10

An approximation of e with n = 10 is 2.59

Enter a positive integer for n: 30

An approximation of e with n = 30 is 2.67

Enter a positive integer for n: 100

An appoximation of e with n = 100 is 2.70

In the illustration below, the user

•  Chose Exponential function;

-   Whenever prompted, entered a 4.6 for x.

•  Chose Exponential function again;

-   Whenever prompted, entered a -2.3 for x.

•  Chose the Exit Program.

>> eapplication

Please enter a value for x: 4.6

Value of built-in exp(x) is 99.48

Approximate exp(x) is 98.71

Please enter a value for x: -2.3

Value of built-in exp(x) is 0.10

Approximate exp(x) is 0.10
