Homework Statement


I have two equations and I want to write them in terms of |0> and |1> as a function of |b> and |d>
note: |i> is a kent or a qubit

Homework Equations


|b> = cosα |0> + e sinα |1>
|b> = sinα |0> + e-iβ cosα |1>

This is a linear equation system, if you attend a quantum mechanics course you should know (or be able to figure out) how to solve them.

I didn't take the quantum mechanics course but I would like to know how can I solve this
 
It looks like quantum mechanics. Anyway, systems of linear equations are way more basic than trigonometry and complex numbers as well.
Wikipedia has an introduction.

You have 2 linear equations in 2 unknowns, so you learned how to solve that type of problem back in early high-school.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
