How To - Complex Numbers
There is of course lots more to it than the few tutorials I can upload - especially since right now I am really busy studying for the exams to come, but here you go!
A How-To about calculating with Complex Numbers (takes up to 10min to understand)
The first part here focuses on complex numbers in their algebraic form, I will edit this tutorial however, to show you the polar-coordinate form, as soon as I have time :p
When starting out with this topic, you will soon encounter the variable i .
Because i is defined as i^2 = -1 we can extend our Real Numbers so that the formula becomes solvable: x^2 +1 = 0
If you want to work with complex numbers, these 4 rules will help you solve the test question at the end :)
z = i/(1-2i)^2
(4/25) - (3i/25)
