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.
>> 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
