i had AP Calc and we didn't has no cheat sheet. >[

i took calc in college too. i fail. xD though all the stuff she went through was pretty easy. but i just didn't have the time to re-learn it. 'cause well.. she spoke with the heaviest french accent EVER.

Sorry guys, all the math talk kind of scared me off so I was lurking. xDDDDDD;;;;;;;

AS FOR PAYMENT

I can also pay in arts? xD;;
Though it's not that good.
And, it'll come soonnnn, because I dun have goldies atm.

;D

T'anks, I'll keep that in mind.

wut be La Tale?
I can't play any more MMORPGs, my time is being sucked away! D:
And...zero wasn't it. D:
I have to simplify it.

And if you ever get a zero or have it show up not possible, I would always double check. xD Remembering identities is very important in calculus.
T_T I wish the answer was always zero though.

And I think windy is avoiding her thread. :lol:

Oh, And Windy, the TI 89 and HP 49g and 50g(I am not sure if any other HP models have it) can solve a lot of the calculus for you. Not all, but in the beginning with derivatives, before it gets too complicated to just punch in yes. xD So, it can help check your work for a good portion of calculus. Do not solely depend on it though. I forgot at which point it stops being dead on. xD I think it was mid way through with us. But it is somewhat of a good investment.

Woahhhh. o-o
I WANT THATTTTTTTTTTT.
;-; </3
I only have a Ti 84. D:

And I lose things, so...
xD;;;

Winter; HELP HER. i told her i would. but then she read me this problem. and i'm like wtf are the directions? XD so i was all lost. i tried to solve it using some methods but .. yah know they usually have directions!! >__>; so being the stupid me that's not that good at math i failed. lol

Awwwwwwwww.
The directions were simply to "simplify".
But I dunno the identities of sin 4x and whatever. D:

Awww.
D:
I had a good teacher, but I didn't really commit the stuff to long term memory.
xD;

:lol; Sin 4x isn't an identity. :lol:

It isn't? D:
I thought it was supposed to be like...
sin 2x.

but like..doubled? o-O?

I DUNNO.
D:

Anyway, I skipped that problem.

...what does (f-g)(x) mean?

Like.
f(x) - g(x)?
D:

-joins the club and wears a shirt with a capital F for FAIL-
LOL


WINDEH! :drool:

well...it is. But it isn't an identity. You have to break the equation down into a known identity, which brings you to sin 2x. xD Windeh, make a group thing. xD I don't think the mods will appreciate us going over this kind of stuff in a thread. :lol: It can get rather lengthy. xD

And is that EXACTLY how the problem looks on the paper?

HAI NESSEH. <3

Yea, but I get posts and perhaps more people visiting my thread this way? :'D

Andd.
YES.
THAT'S EXACTLY.
HOW IT LOOKS
@[email protected]
I solved the easier ones, but when you ask me to apply the basiccc principles, its' like @[email protected];.
-bad at applications-
@[email protected]

SIMPLIFY
61. sin 4x / (1+cos4x)

62. 2cos^2(x/2) - 1

@[email protected]
That's all the directions they give me.
;-; </3

wow man, i've totally forgotten all my math stuffies :o

edit: google searches work wonders tho:
(f-g)(x) linky example



#61 linky here
tan (X/2) = + or - SQRT [ (1 - cosX) / (1 - cosX) ]

= sinX / (1 + cosX) = (1 - cosX) / sinX



edit2: #62 check out linky here

Hi Windy~ XD

Hai Winter. ;3

@Windy: I can help you some with your math. And you don't have to pay me. It's been a few years, but I got good marks in all my math classes. I can't help much with actual calc though. lol I only made it up to pre-AP trig/pre-calc. : 3 So anyways, if you have some questions just shoot 'em my way. <3

When I have time I'll draw you art? :3
..."art", since I can't draw, but still. xD;

Kay, another problem I don't really know how to approach:

The surface area of a square prism is a function of the length of a side, s, of a square base and the height, h, of the prism.

a. give a rule for thie surface area function.
my problem: Rule? Does the teacher just want the function that'd work for it?

b. find two pairs (s, h) for which A(s, h) = 100.


So.
for A, it'd be 6(sh).
Since it's a cube.
But I dunno about the "rule" I'm supposed to give. @[email protected]

b. I just plug stuff in, right? :3

I did this already, but my friend got a different answer so...
D:

for that prism function... i don't think it's 6sh. Because it's not a "cube". The base is a square, but the height is different, right? At least that's what i'm imagining in my head.

i think it's more like A(s,h) = 2s^2+4sh??

but i really don't get it lol xD




and for the A(s,h) = 100... yeah you'd set the function = 100. And then just figure out 2 sets that will work?

o-o

You're right.

I looked up the definition of a square prism, and it doesn't really HAVE to be a cube...

Cool.
Darn, the friend was right after all.
xD <3

T'anks so much! ^^ <3333333

yeah i was rather confused too about it calling it a square. :o

Yea, weird stuff.
o-O.
Might as well call it a rectangular prism.
x3

laskdjflasdlfkjas
I freakin HATE math.
x_x
T'anmks for all the halp! ^^

I'm now working on sin 4x / (1+cos4x)

So sin 4x = sin 2(2x) = 2sin (2x)cos(2x) = 2(cos x sin x)(cos^2 -sin^2)

Then the 1+cos4x = 1 + cos 2(2x) = 1 + (cos^2 2x - sin^2 2x) = ???

wasn't that the problem above? you cannot use the formula i posted?
tan (X/2) = sinX / (1 + cosX)

therefore sin 4x / (1+cos4x) = tan2x??





edit: if you actually need to prove it... perhaps check out this linky. i didn't read that whole link thru tho. but most profs will accept formulas as givens i think.

gah, i'm letting all your hardwork go to waste.
x_x


Ohmygod.
o-o

HOLYCRAP

o-o
WE DIDN'T LEARN THAT

I'm so sorry, you're right again.

In my book, tan x/2 was equal to something else.
And when simplified, it turns into that.
o-o

WE DIDN'T LEARN THAT
aslkdfjalsdflajf

Thanks. ^^

LOL it's ok xD there's just too many trig formulas, i don't remember any of them @[email protected];; but google is your friend :drool:

Elie i love yu.
xD <3

Yu're amazinggggggggggggggggg.
8D <333

I think I'm going to take a break from math, and start on Spanish.
x-x

WAH too cute! :love: LOL spanish, that can't help you on xD i knows like absolutely no spanish :o

Unfortunately, that's about the extent of my art skillz.
._.;

I'll see if I can do anything better for you, since you've helped me a lot. <3

Hahaha.
I hate spanish, but since it's kind of close to English, I took it.
xD

lol it's cute tho! and no worries, i'm just bored xD feeling sickish so not working today @[email protected];;

i took 4 years of japanese but i remember nothing :o

Hahah, awww.
xD
Japanese is really cute.
>w<

DOES THAT MEAN YO UCAN UNDERSTAND JAPANESE DRAMAS? :0

Aww.
Feel better soon.
;-; </3

no D: i can perhaps understand 1/3 of it... or less... @[email protected];;

oooh lunchie ttyl! :drool:

Kay, bye! ^^

Have a nice lunchh.
x3

I had potstickers.
<3
