The imaginary part of complex

Parent Previous Next

The formula of a real calculus is not allowed to refer to a complex number. Thus if you want to use the imaginary of a complex number you have first to create a modulus of complex


You can then refer to this calculus (which is a real calculus) in another real calculus.

Here is an example :


Let's a complex number named z has been created.

You wish to create a point coordinates of which will be the double of z real part.

You must use of the calculations expandable bar (third from the bottom).

In the field Name of the calculus, type a.

Press OK.

When you will create a point by it's coordinates you will specify 2*a in the fields x-coordinate and y-coordinate.
