Geez, 35th week of school. This is kinda depressing...
This week was completely intense and it showed me that I'm really not ready to take this test. 4 days of testing and 1 day of career thing...fun.
Anyway, I did learn something this week about calculus: I love my calculator just about more than any other technology...just about.
My mind blanked on how to do a few simple things that I've relied on my calculator for, but during the practice APs I remember? I think it might have been the intimidation factor...
Also, the free response was killer...I think I may need to memorize the wiki problems, but I might need a little more help?
I don't have my APs on me otherwise I'd ask a ton of questions, but I mainly need help on the non-calculator portion. I've been spoiled into relying on my calculator for everything...I need someone's help to relearn how to do things by hand.
Also, I learned that the trig chart NEVER goes away....EVER...
I must pull mine out from the abyss and relearn it
Things to remember on Non-Calc Multiple Choice:
Trig Chart
Derivative formulas
How to solve for x
How to graph
How to find the limit
Things to remember on Calc multiple choice:
Everything
Bring batteries
Always make sure you actually have a calculator...don't walk into a room unprepared..
I hope everyone has a good week! Don't somehow burn yourself on something and don't forget corrections!
[[btw, bold is things I really need help with]]

How to find a limit:
ReplyDeleteI'm assuming you are talking about finite limits, limits in which it is approaching a number. All you have to do for these is plug in the number into the equation and simplify. If you get 1/0, it's DNE or nonexistant. If you get 0/0 or infinity/infinity, take the derivative of the top equation and then take derivative of bottom equation and plug in again. If you still get 0/0, repeat the process. This is called L'Hospital's rule.
to help with calculator section/things I learned:
ReplyDelete1. use the intersection function on your calculator to find bounds for integrals
2. don't forget about your zero function and table too
3. if you are given a graph and you can make shapes underneath the curve like rectangles and triangles, that finds the area
4. let your calculator integrate for you when possible
