Homework Statement
If |A> = x |B> + y |C> where |B> and |C> are orthonormal, then what happens when <A|A> ?
The Attempt at a Solution
Would <A| = x* <B| + y* <C|?
I'm not really sure where to go from there

Write down <A|A> with your <A|, and use the distributive property of the scalar product:I'm not really sure where to go from there
I did mean orthonormal, ahh confusion! thanks :)yup!
that's what's so beautiful about orthonormal systems!
(erm … you did mean orthonormal, and not just orthogonal? )
