Homework Statement
Hello, I am stuck on four equations for which I must find the coefficients A,B,I,J.
I have tried using latex but the commands don't seem to work.
Homework Equations
Four equations:
[tex] A+B = I+J [/tex]
[tex] \frac{\alpha}{k}(J-I) = A - B [/tex]
[tex] D = Ie^{ia(\alpha-k)} + Je^{-ia(\alpha + k)} [/tex]
[tex] D = -\frac{\alpha}{k}Ie^{ia(\alpha-k)} - \frac{\alpha}{k}Je^{-ia(\alpha + k)} [/tex]
The Attempt at a Solution
I = [2B + J((alpha/k)-1)]/ (1+ (alpha/k))
i got this from setting 1 and 2 equal to A then solving for I but i don't know where to go from here. Any tips?
