Argand diagram
Hi I would really appreciate your time for this, I would really like to know if my interpretations on the argand diagram are right!
Where w and z are complex numbers,
Let arg(z)arg(w) = 90 degrees where arg(z) is represented by theta and arg(w) is represented by alpha.
I drew two interpretations of arg(z)arg(w) = 90 degrees on the argand diagram, am I right in the images below?
I am not sure if I am right as they both yield different equations like one diagram shows thetaalpha to get 90 degrees whilst the other alphatheta to get 90 degrees..I was wondering if this is the reason why you would insert a modulus, alphatheta = 90 degrees..can someone help me out?
Thank you so so so so so so much, you dont know how much this means to me!
