\newcommand{\mean}[1]{{<\!\!{#1}\!\!>}}

\newcommand{\braket}[2]{{<\!\!{#1|#2}\!\!>}}

\newcommand{\braketop}[3]{{<\!\!{#1|\hat{#2}|#3}\!\!>}}

\braket{\phi}{\psi} \equiv \int \phi^*(x) \psi(x)\,dx

[/tex]"

Ive seen such equation for Bra/Ket vectors and that confused me, sine i failed to identify this code

latex \left | \psi \right \rangle /latex

[itex] \left \langle \psi \right | [/itex]

latex \left \langle \psi \right | /latex

[itex] \left \langle \psi \right. \left | \psi \right \rangle [/itex]

latex \left \langle \psi \right. \left | \psi \right \rangle /latex

Note: The "latex" and "/latex" should be enclosed in square brackets to make the equation appear.
