Looking back:
I can't tell what this thread was about...
#Mistakes

Answer 1

i am bored ...

Answer 2

I'm boreder!

Answer 3

I think it's 10 Steps. Not sure tho.

Answer 4

we have a winner!
its 10 steps

@Mimi_x3 can still provide explanation

Answer 5

I have never done such problem before; i dont understand what to do lol

Answer 6

\[a^2+b^2=c^2\]
\[20^2+15^2=c^2\]
\[400+225=c^2\]
\[c^2=625\]
\[c=25\]
Therefore Camp A to Camp C is 25 steps.
Camp A to Camp B to Camp C is 15+20=35 steps
Therefore 35-25=10 steps.

Answer 7

Boom shakalaka. Pythagoras theorem all the way.

Answer 8

lol, i feel stupid

Answer 9

\(15^2+20^2=c^2\)
\(15^2+20^2=625\)
\(sqrt(625) = 25\)
@Azteck you ninja'd me :|

Answer 10

ANother problen; opp!!!

Answer 11

Okay. :/

Answer 12

Solve this integration \(\huge\int_0^1 \frac{x^{2012}}{1+e^x}dx\)
Show your work.

Answer 13

integration by parts
\[ \int x^{2012}* \frac{1}{1+e^{x}}\]

Answer 14

lets see
\(u= 1/(1+e^{x})\)
dv= x^{2012}

Answer 15

you do it yourself lol @Opcode too lazy

Answer 16

You think I even know this math?
I was giving you a question that I didn't even know existed :|
What math is it? <-- Answer that.

Answer 17

Integration...finding the area of a given crap.

Answer 18

What happened to rectangles? :O
Simple to find area... Why would anyone need this?

Answer 19

well in higher level maths; you have to find the area of a given thing..like a curve thingy lol

Answer 20

What curvy thingy?
How can one even find a area of a line? This make no sense.

Answer 21

so you see
http://www.wolframalpha.com/input/?i=y%3Dx^2%2C+y%3Dx
you are trying to find the area bounded by the two given lines; hence you use integration...it is like using small rectangles thingy..but instead of that..you integrate from the given point that is called limits.

Answer 22

Oh... Okay?
Wow...
Do you think they would have this in Khan Academy?
Also what is this algebra? Calculus?
Or is there a math called "Integration?"

Answer 23

Enjoy!

Answer 24

You're officially trying to kill me :|
Opcode doesn't even know basic Trigonometry... How would Opcode even begin to understand calculus?

Answer 25

No need trigonometry.

Answer 26

infact, i skipped the basics of maths to calc lol

Answer 27

...
What's that "E" looking symbol?

Answer 28

Where is the \(E\)?

Answer 29

The thing that goes like a M but its like:

Answer 30

SIGMAAAA!!

Answer 31

Summation symbol lol

Answer 32

So I have to learn what that is first? -.-

Answer 33

its basically summing up

Answer 34

Oh...
What's this big fancy line mean:
\(\huge\int\)

Answer 35

Integral sign lol

Answer 36

Trying writing it on paper; its cool :D

Answer 37

@Opcode People got lazy so they turned it into that S sign. It's a true story.

Answer 38

lol, why lazy

Answer 39

What's it used for O.o?
