sinX = 6
n

PROVE

 

[A2]

(1/n)*sin = 6
(1/n)*n*six = 6
(n/n)*six = 6
six = 6

PROVED SUCKA

Hahahaha at first I fell for it ;DD nice one

 

[Vinzyboy23]

I'm sorry, I'm minimal. 288 or 2?

 

[Tomstoiler]

I've got another one:

x+y=z

3x-2x+3y-2y=3z-2z

3x+3y-3z=2x+2y-2z / ive just put all the 2s and 3s on one side

3*(x+y-z)=2*(x+y-z) / divide with (x+y-z)

3=2

where is the mistake?

Yeah...

Hey look wut I did- oh SHIIIIIIIII-

Okay, I'll ask an easy question.

f(x) = cos(x)
F'(x) = ?

 

[T[h]E Dis[as]teR]

that last question is silly

CALCULUS FTW! I have a crapload of Free Response Calc problems from AP exams from past years if you guys wanna try them out

 

[BeefThief]

-sin(x)

It's just sin(x). F'(x) implies an antiderivative, so it would be similar to asking "the derivative of what is cos(x)", which is sin(x).

correct your self before some one reads it, hurry up

I thought that was right :|

I think he probably just ignored the capital F and the lowercase f. My teacher told me to use F'(x)=f(x) as a guide to solving problems involving differential equations. In that case, it WOULD be sin(x). If they were both f(x), then the solution would be -sin(x).

ops didn't notised the F''''''''''''''''''''''''''''''''''''''''''''''''''''''' it's so small
whaterver

Anyone else taking the AP Calc test next week? I doubt I'll do very well, but I feel like I need to take since I have so much time invested in studying this stuff.

 

[T[h]E Dis[as]teR]

my tests are starting 6th/jun, 2 months vacation to study

I'm taking Calc AB My teacher's giving us a bunch of problems from past exams. I HAVE to get a good grade on it because I'm aiming to pass out of my first semester of calc in college, and math and science are my strengths for the most part. I would've done BC as well, but it's not available at my school.

 

[BeefThief]

Yeah, my teacher is giving past tests, too. Unfortunately, after all those problems, I still can't do the open-ended.
