A range of algebraic and graphical results relating to complex numbers can be obtained using a ClassPad. This is done by firstly ensuring that the ClassPad’s setting are correct, and then entering the relevent information. The settings required are shown below:
When looking to obtain graphal results in the complex plane using a ClassPad, firstly define z as a complex number x+yi.
With that done, constraints on z can be entered, and then the ClassPad’s output can be expressed in the form “y=…” so that its graphical meaning is apparent. If this output is then dragged into a graph window, then a graph can be obtained.
Two examples of this process are shown below:
