[QUOTE=40kplayer;17839240]You know what's even less fun?

The Chain Rule.[/QUOTE]

Nah, the quotient rule is less fun than that. The chain rule is simple and useful.

[40kplayer]

Hooray for calculus!

This is my favorite thread.

3D Graphing is the best kind of math BTW.

E^(Pi I) == E^(2 I Integrate[Sin[t]/t, {t, 0, Infinity}])

yeahhh

[Lt_Captain]

The probability of two independent events happening together is just the probability of each event multiplied together.

[QUOTE=Archive;17830584]Lets do fun math!

x^(-1 * sqrt(-1)) makes an insanely pretty graph by the way.

Do shitty math and fun stuff here, I'm watching you.[/QUOTE]

Why would you take sqrt(-1)?

It's answer is -1i

[mr-kaki]

pi = 3.141592654
Those are the only digits I remember.

Cause it's fun

Not true.

Noo.

[evilking1]

[QUOTE=Rad McCool;17841657]Not true.[/QUOTE]

Well it's quite that, the closer you go to 0 from right side it's going nearer infinity, from the left side it's going nearer -infinity

[hydra263]

3lim n->infinity (n-1/1) = 3

[JohnnyMo]

[QUOTE=hydra263;17842923]3lim n->infinity (n-1/1) = 3[/QUOTE]

False.

[Rad McCool]

[QUOTE=evilking1;17842908]Well it's quite that, the closer you go to 0 from right side it's going nearer infinity, from the left side it's going nearer -infinity[/QUOTE]
Sure,
a/x = ∞
x -> 0
lim

But it's not the same thing.

[GrandeVinale]

i = sqrt(-1)
i^2 = -1
i^3 = i^2 * i = -1*i = -i
i^4 = (i^2)^2 = 1
i^n = i^(n mod 4)
Complex numbers are awesome.

also d/dx (e^x) = e^x

[Scythex]

HAHAHHA LOOK AT THIS!!! HAHAHAHa

0 divided by 0 = OOOOOOOHHHH SSHHHHIIIITTTT

HAHAHAHAHAHHAAHa

[MightyHaku]

[QUOTE=Scythex;17843298]HAHAHHA LOOK AT THIS!!! HAHAHAHa

0 divided by 0 = OOOOOOOHHHH SSHHHHIIIITTTT

HAHAHAHAHAHHAAHa[/QUOTE]

take x = 0
x/x = 1;
0/0 = 1;
What's so oh shit about that?

[Rad McCool]

[QUOTE=MightyHaku;17843414]take x = 0

x/x = 1
Where x ≠ 0

[MightyHaku]

[QUOTE=Rad McCool;17843468]x/x = 1
Where x ≠ 0[/QUOTE]

Why is this so? i/i = 1, why can't 0/0 = 1?

[QUOTE=MightyHaku;17843589]Why is this so? i/i = 1, why can't 0/0 = 1?[/QUOTE]
Since anything divided by 0 is undefined.
0/0 might aswell be 35 (0 * 35 = 0).
0 * x = 0
x can be anything.

No worries.

[UtaxDoom]

Following equation equals 0: (3x+1)(6-2y)-2(3-y)-6(3x-xy)

[Rad McCool]

[QUOTE=UtaxDoom;17843806]Following equation equals 0: (3x+1)(6-2y)-2(3-y)-6(3x-xy)[/QUOTE]
That's not even an equation, it's a polynomial. And its value can be anything since x and y are undefined.
Or do you mean:
(3x+1)(6-2y)-2(3-y)-6(3x-xy) = 0
?

[QUOTE=JohnnyMo1;17839380]Nah, the quotient rule is less fun than that. The chain rule is simple and useful.[/QUOTE]

Chain rule is piss easy compared to the quotient rule.

But the quotient rule isn't that difficult.

[JohnnyMo]

[QUOTE=BaconDioxide;17843992]Chain rule is piss easy compared to the quotient rule.

No, just irritating to use.

[BaconDioxide]

[QUOTE=JohnnyMo1;17844039]No, just irritating to use.[/QUOTE]

Amen to that. All the answers from the exercise I was doing on it are all like a long string of variations on

(3/2(3x-3)^-1/2...) divided by whatever squared

etc.

Looks like an absolute bloody mess. And I thought the product rule was bad. :v:

Oh well, onto RATE OF CHANGE now. More calculus woo

Never was a math guy, I'll leave it to the number crunchers to do the math for me.
