Why Doesn't MathType Recognize Dirac's Bra-Ket Notation?

[flydream19]

Hey guys I'm new here and I've been using MathType for all on-screen math. For some reason PF doesn't recognize the built-in Dirac's bra-ket notation. (i.e. <\psi|) So I've included my equations and solution in the format of images, hopefully it isn't a problem.

Sorry I just realized a typo in my solution, but it doesn't affect the result:
The typo is at where I said: "Then I moved on to the right side:"
\alpha^*=6-5i<br />
<br /> \beta=1+i<br />
The beta should have a complex conjugate symbol (*):
<br /> \beta^*=1+i<br />

In your initial calculation of &lt; \alpha \omega |, the middle term is wrong. I haven't checked over your math any further than that and the &lt; \beta \omega | calculation.

p.s. Moderator's note: I am moving this to Advanced Physics -- it doesn't really look like Introductory level physics to me, which we consider to be through (U.S.) college sophomore level.

p.p.s. In LaTeX, simply typing "<", "|", and ">" for bras and kets seems to work okay, but not great.

As another \LaTeX option is to use the /langle and /rangle together with "|" to do Dirac bra-ket notation.

For example,

[tex] \langle x | y \rangle [/tex]

yields
\langle x | y \rangle

[Edit: I still can't get them to scale up automatically though, in case the things in the bras and kets are larger and more complicated.]
