In regards to #12 it is a just the quotient rule. Don't worry about simplifying just get a crude derivative and plug in your X-value. This gives you the slope. Then plug in the X-value into the orginal equation to get the Y-value, and now you have a point and a slope.
for the hw quiz tomorrow...will it just be on page 155? but both of the assignments? because the rest of the hw before that was from last week..and isnt implicit...
can i come in for help tomorrow morning again? i have a lot of questions and i have no idea whats going on..help me please! missing school blows :( then maybe i can take that quiz 6th period?

#27, Treat theata as a variable. You could replace them with X's. Then you should have just a simple product rule. Hope this helps.
ohhh okay, we will try it! Thank you!! :)
Have a safe drive to St. Louis!

No page 155 on tomorrow's HW quiz. Focus on the implicit but I might put a simple problem from the chain rule section as well.

I will see you tomorrow morning. I will be in room 350 at 6:45.
question...are u free during advisory for us to come in and ask questions??
Sure room 352!
thank you! you are too kind!
question...for #20, we are at the equation t= (6-x)/5 + [(4+x^2)^1/2]/2...
are we supposed to get common denominators before we differentiate?
when we didnt, we got x= (1/6)^1/2...when we plugged this back into the equation, we did not get the right answer...
any insight?????
:(
thanks
