jquery in wordpress

[spc1029]

I am trying to use the jquery library in a wordpress theme that I am working on. Does anyone know if wordpress already has jquery installed in it or am I just over thinking it? It will not work when I just add the jquery file to the directory and link to it in the page.

I figured it out. for some reason in version 2.9 instead of using the $ when writing jquery you are supposed to write jQuery. The most annoying problems always seem to have the most simple solutions.
