Homework Statement
Consider a three-dimensional vector space spanned by an orthonormal basis [itex] |1\rangle, |2 \rangle, |3 \rangle [/itex]. Kets [itex] |\alpha \rangle, |\beta \rangle [/itex] are given by
[tex] |\alpha \rangle = i|1\rangle -2|2 \rangle -i|3\rangle, \qquad |\beta \rangle = i|1\rangle +2 |3\rangle. [/tex]
part a) Construct [itex] \langle \alpha| \text{ and } \langle \beta | [/itex] (in terms of the dual basis [itex] \langle 1|, \langle 2|, \langle 3| [/itex]).
The Attempt at a Solution
I just want to check that I understand this correctly. Is the Bra the row vector that is basically the complex conjugate of the Ket, leading to the inner product? In this case,
[tex] \langle \alpha | = -i \langle 1 | -2 \langle 2| +i \langle 3| \qquad \langle \beta | = -i\langle 1| + 2 \langle 3| [/tex]
