## Execute a exponential function program, MATLAB in Engineering

Assignment Help:

Execute a exponential function program:

Running the script will take up the menu as shown in the figure: Then, what happens will totally depend on which button(s) the user pushes. Each and every time the user pushes a button, the suitable function will be called and then this menu will appear again. This will carry on until the user presses the button Exit Program. Illustrations will be given here of running the script, with various sequences of button presses.

In the illustration below, the user

•  closed the menu window which origins the error message and brought up a new menu.
•  chose description.
•  chose the exit program.

>> eapplication

Error - please selects one of the options.

The constant e is known as the natural exponential base.

It is used broadly in mathematics and engineering.

The value of the constant e is ~ 2.1718

Raising e to the power of x is so general that this is known as the exponential function.

The approximation for e is found by using a limit.

The approximation for the exponential function can be found by using a series.
