this is where felt and i discuss math
(34x12 + 76x9 - 41x4) / (4x3 + 7x)
Find the end point
ok go you guys.
cis(pi)
So today I had to find how out long the carbon 14 was there.
We were told that it was at 30% of its previous mass and the halflife was 5700 years.
I got an answer of about 12,000 years.

i luv logs
did u hav to do work with newton's laws
those are so cool
x=jmv290
find the derivative

This is algebra II stuff.
Come on guys impress us for reals. Show us something with Calc III.

first i divided 72 by 5700 and got .01 and then was like ok thats the rate of decay then i was like
P=P
oektand then i was like ok
30=100
e.0001T.3=
e.0001Tln(.3)=.0001t
ln(.3)/.0001=t
and it was a little more than 12k

None of us have been in a "Calc III." psyduck;
I was in AP Calc, but I don't remember a whole lot of it.

I never have to take another math class again, so I let myself forget. I got a 4 on the AP Exam, so I was done with college math credits before even going to college.

same thinglol
I'm taking high school level calculus for practice for AP Calc. Don't make fun of me. ;_;
Pointless math is... pointless.
∫endu = en+ C
If f is continuous on [a,b] and if F is an antiderivative of f on [a,b] then:
a∫b f(x)dx=F(b)-F(a)

Wait, there's math that had a point to it?

From what course is this?
Quote from: Albel The Dark on February 06, 2008, 05:19:05 PM

Anywhere from Precalc to normal Calc.
And you said you wanted Calc III stuff?

Ok. The point of that wus?
To tell you that nobody's going to give you anything from a "Calc III" class. I figured that was fairly obvious.
Quote from: Albel The Dark on February 06, 2008, 05:27:29 PM

No...
AP Calc is a High School class.

I meant like Clalc, because i kinda remember you talking about having Calculus right now..

i fucking hate math.
y=f(x) is differentiable at x or f(x) has a derivative, Xo, if
lim h->0 -
f(xo+h) - f(xo)
h
=
lim h->0 +
f(xo+h) - f(xo)
h
I haz precalc.

i luv differentiation
A fuction is said to be continuous on a closed interval, [a,b] if the following conditions are satisfied:
1) f is continuous on (a,b)
2) f is continuous on the right at a
3) f is continuous on the left at b
also lol
lim h -> 0
Sin(h) =1
h

I should have used that as an answer.
"I know that the answer would result in a number larger than 6,000 years. God created the world 6,000 years ago so it is impossible for it to be any older"
