Complex Numbers in Equations
You can type complex numbers in equations. When an equation is displayed, all
numeric forms are shown as they were entered, like xiy, or rθ a
When you evaluate an equation and are prompted for variable values, you may
enter complex numbers. The values and format of the result are controlled by the
display setting. This is the same as calculating in ALG mode.
Equations that contain complex numbers can be solved and integrated.
