come prove weed doesn't "slow you down"

Unfortunately, it is not possible for me to prove that weed does not slow me down. In my case, it is a firmly established fact.

It is not impossible that, if I put my mind to it, I could make some sense of your mathematical conundrum, but I do not deem it as worthy a way to spend my time as, say, twisting up another doobie and watching Weeds or playing Deus Ex..

 

to answer the OP

Q=X+Y
X=At^2 (my notation for A times t squared)
Y=B/t^3 (that's B over t cubed)

Q(t)=At^2+B/t^3 (Q of t is this equation)

Q(1) = 35
Q(2) = -15

plugging in these values we get 2 equations

1. A+B=35
2. 4A+1/8 B = -15

subtract 8 times eq2 from eq1

-31A = 155

divide out -31

A = -5

Sub A = -5 back into eq1

-5 + B = 35

add 5 to both sides

B = 40

now we have the equation for all Q by subbing back into Q(t)=At^2+B/t^3

Q(t) = -5t^2 + 40 1/t^3

Plug in the -1 value in the question

Q(-1) = -5(-1)^2 + 40 1/(-1)^3 = -5-40 = -45

And when t is -1, Q must be -45

Anyway skip, I'm surprised at you. People need math for science, engineering and many other areas. This is just algebra, it is the foundation of many types of math. You could ask that same list of questions about literature, art, everything. Personally, I have used algebra, trigonometry, calculus, differential equations and matrix analysis for my whole career and several good projects. A controller for a machine that can do surgery on a beating heart without cracking the patients ribs, a whole line of testing machines that make bikes safer and help us develop natural composites. I am a controls engineer and I have consistently refused jobs involving development of weapons of war, strip mining, and production of anything else I disagree with. Math is a type of knowledge, and knowledge is power, a kind of power that goes to individuals that work hard for it rather than people who just buy and bully for it (though admittedly they can usually hire the people who worked hard for it) I would think you of all people would support that.

 

Well thank you very much!

Yes, I would have to agree, skip...... I'm a math idiot, but I still find myself using algebra (how much of it I can, anyways) all the time, actually, solving the sort of simple equations that comprised the bane of my existence about a decade ago. From working on my electronics to my car, it's useful. It's the basis for solving all of the problems you listed, and as pablo said, we do lots of things, (and study them in institutions for the purpose of pushing them as far as possible) that may or may not have any effect on those problems directly. Indirectly, they may exercise peoples brains, etc, in ways that even help. But either way, it doesn't HAVE To do anything, it's certainly not NEGATIVE to do, anyways.

 

Man, wish I could help but I've only got a fourth grade math level Deductive reasoning would say that if you slow down people will notice that you're slow, and no one has ever noticed that I'm slow so it would appear that in reality you don't slow down at all, you just think you do.

 

No problem RooR, lately I've been working on vibrations, which involves a lot of differential equations, system modeling and all kinds of principals which I'm not going to bother naming, so this was a fun one page problem.

For anyone who wants to learn math better I recommend "the easy way" book series. I left high school with almost no math skills, went through algebra the easy way, which gave me what I needed to get started in calculus (there are prerequisites but they waive them if you ask nicely) and went from there.

 

Hm, cool. I think I'll check that out.

 

I say "fuck no" to math, man. I got all my math credits done and got the fuck out of math classes forever.
