Hello, just a quick question.
I have two complex numbers (say z and z'), and I want to find the area of the parallelogram that is generated by the two complex numbers (written as vectors, ie, if z = x + iy is a complex number, then the vector is (x,y)).
Now the area of the parallelogram generated by z and z' is |z x z'|
However, when I compute z x z' I get what I would consider a "scalar" and then I am asked to take the "magnitude" (or is it "absolute value") of this "scalar." Do I just take the "absolute value"?
For example.
say z = 1 + i, and z' = 1 + 2i
then z x z' = (1)(2) - (1)(1) = 2 - 1 = 1.
The area is |z x z'| = |1|. Is this the absolute value of 1 (which would equal 1) ?
Thanks.
