If I convert the denominator as given in the problem I end up with: i r^2 sin(x)+r^2 (-cos(x))+1 I don't see how I can make a conjugate with 3 variables here? Am I missing something? I have went over this several times in attempt to make sure I hadn't made a mistake......
1. Homework Statement
Express (see attachment) with a real denominator
2. Homework Equations
Not sure if there is really relevant equations to use here.
3. The Attempt at a Solution
First I multiply the top and bottom by the exponential. That gives me e^ix/(e^ix-r^2). I...
Yeah but the question is what is What is arg(iz) so doesn't that mean that I mult i times 2-i to give me 1+2i?
I think what you just said would be for arg(z). correct?
1. Homework Statement
I need help on a little review please. z=2-i What is arg(iz)
2. Homework Equations
Well iz= 1+2i
3. The Attempt at a Solution
I think this should end up being arg(2i/1) But this doesn't seem to make sense because I am wanting to find an angle here...
