Gents how do I write Bra and Ket vectors here

Gents how do I write Bra and Ket vectors here, I ve gone through the help documentation, but I could not find, I saw one equation as an example but I failed to identify Bra and Ket associated codes

Er.. what's wrong with using "<", ">", and "|"?

"
\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

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

\left | \psi \right \rangle

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

\left \langle \psi \right |

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

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

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.

Try this.

\frac{d}{dt} \left| \psi \right> = \left| \frac{d \psi}{dt} \right>
