Wow
Only one more week until we can finally be freed from school for two entire weeks! I'm so excited!!
This week we spent...doesn't stuff? I don't actually remember...so let's skip to Friday
Friday: Beast packet :D
Saturday: ACT + Subway (omg $5 6inch..YUM!) + PJs + Walmart (1.5 hours, with Mal's mom to get EIGHT things...) + New Orleans Hamburger (YUM! SEAFOOD!) + Movies (standing outside trying to decide what movie to watch, New Moon or the Blindside...for...thirty...minutes) + NEW MOON! FINALLY! + Calculus packet again
Sunday: Calculus packet + English packet + Tic Tac Toe + Calculus packet..againn
So..yea...that's all I have to say :)
Hmm...what do I know that I can explain?
Umm...Riemann Sums?
I'm pretty sure that's way over-done, but I have no idea what else to explain! =/
Delta = b-a/n (top number above S minus the bottom number below S divided by the number of intervals)
LRAM: delta(f(a)+f(a+delta)+f(a+2delta)...+f(b-delta))
RRAM: delta(f(a+delta)+f(a+2delta)+...f(b))
MRAM: delta(f(mid)+f(mid)...)
Trapezoidal: delta(x)/2 [ f(a) + 2f(a + delta x) + 2f(a + 2deltax)
+ f(b))
Just don't forget to not go over the amount of intervals you have (n).
Now, I've got major questions
1. Trapezoidal graphs...where can I get the software?
2. What's deltax? is that the same thing as delta..???
3. GRAPHING! AHHH!!
4. Also, for limits, are they asking for the open circle or the closed circle? I always get confused! And each time I change it, I get it wrong..Help!!!
5. Another thing for limits, what do you do if it's over zero? I remember something about it...did she or Alex go over that? Anyway, I can't find those notes and I didn't get it before...=/
Okay, this is my extreme problem:
I've never been able to remember the steps for math
I can do it if I know what I'm doing (makes total sense right?)
But I can't remember the steps
Does ANYONE have a way to do remember?? =/

1. Several sites have the software but my computer doesn't work with the upload software to the calculator. I believe John is working on that.
ReplyDelete2. Delta x is b - a/n where b and a are your x values [b,a] and n is the number of intervals
4. A limit refers to the open circle typically. It's whichever one is attached to the graph with the exception of a jump which doesn't have a limit.
5. If you get 0 in the bottom you have to factor the top and bottom and cancel or use your calculator.
