A'ight thanks man. I think analytical geometry was actually offered as a class at my sister's high school, but I may be wrong since I'm going to a different school than she did. I wondered if it was supposed to be "Plane" and not "Plain" on my schedule. Someone made a typo. Continuing onto what you said, linear algebra would mean mostly algebra 1 correct? Haven't taken algebra 2 so I don't know what it's all about. I'm actually posting this in my computer class having just finished our final. I start P&S Geometry Monday. Edit: Didn't mean to make a new thread. For some reason when I logged in it got all messed up. These school firewalls and protection software(s) make it hard for any message board to work properly. So just take what I said in reply to my other thread.
