No, it wasn't.

Correct is: a_n = 3*2ⁿ*n!

The problem was that (-1)! is not defined.

oh ok. I guess if you mutate mine a little bit it was right all along.

and how the hell do you add superscript..

If you can quote superscript you can write superscript.
Just look at the tags used there.

yeah i just noticed. lol.

What was just messing with my mind is that my equation can be turned into your equation with a few operations:
6n*(n-1)!*2^n-1 = 6 * (n*(n-1)!) * 2ⁿ/2 = 3*n!*2ⁿ

But my equation won't work with n=0 where yours does.

Im just dumb when it comes to math lol

Finally, you guys are fucking geniuses. What math background do you guys have? I know this is fairly easy stuff, probably equivalent to alg 2, but this one in particular was really mind-fucking me.

And since you helped me, subscript is "sub" with HTML tags, or "sup" for superscript.

Thanks fellas.

The Track Carpe Noctum is like traffic but it hink he could of prefected the shit ouf it. but generalllyy its an amazing album...oh and Ten Seconds Before Sunrise is like Forever today TIMES 12

decent thread. I finished my mech. eng degree recently so I have seen my fair share of math.

Question for the math geeks out there. I saw this my on a final I took and have never worked on this before? "3/2!" a factorial of a fraction. I did my research after the exam and it has to do with the gamma function, etc and know what it equals?

http://en.wikipedia.org/wiki/Factorial <--non integer values

My main concern is what class would you learn this in even though we did the typical factorial in HS?

I've a Calc II Final tomorrow morning. If I don't pass it, I fail the course. First time I've ever significantly struggled with mathematics. Damn you v dus and (n+1)s.

I remember finding areas and volume of rings. Not the hardest but having a decent professor helps.

good luck

I've done fine with the homework and stuff, it's the exams that keep tripping me up, and it doesn't help that they're worth such a significant portion of the final grade.

Nor does the fact I'm in a class with a bunch of summer Asian students, putting me significantly under the curve of a class for the first time since Grade 8 woodshop.

You're welcome

I actually don't have that much of a background in math. I've taken 3 calc courses and an Ordinary Differential Equations + Linear algebra course (Partial differential equations next semester...)

Anyway, my approach to solve the problem, ironically, had nothing to do with any kind of formal mathematical algorithm/formula. All I did was take a look at any patterns I could see. I saw that each level was divisible by 3n, and that each level was divisible by (n-1)!, so i pulled that out and saw that the sequence just followed 2^n-1, so put all of it together and do a little bit of manipulation adn you get 3*n!*2ⁿ
