The built-in functions are arranged into eight groups which are commonly found in science and engineering. Help is available on each of the groups individually.
The groups are:
Trigonometric,
Exponential,
Quadratic,
Polynomial,
Modulation,
Fourier Series,
Second Order Step,
Linear.
The ‘User Defined’ group is for you to store your own functions. To do this, save the graph into a folder called “User Defined”. The file will be added to the menu automatically.
