I'm thrilled that they are studying and helping each other.  The AP test is May 19.

so you guys know how in our calculators POdbaby[what they call me--except with part of my real name instead of POd}  had us store those expressions for when you graph in the y= list thing. it's the derivative and double derivative? well yea. i accidentally deleted those and now i'm lost. can someone tell me what they were?! por favor.
