hey 4chan, anon here. the opposite of addition is subtraction.

inverse gamma function where it is bijective

>>8766206
factorial is just a series of multiplications so a series of divisions

define a new operation ? by
a?=a/((a-1)!)

then (a!)?=a!/((a!-1)!)=a

5! = 1x2x3x4x5
so
5!^-1 = 1/1x1/2x1/3x1/4x1/5

>>8766221
congratulations, you're retarded

>>8766576
Pretty sure that was bait

>inverse of differentiation is integration
K then give me a primitive of the Thomae function fagglord.

>>8766206
The opposite of power is log not root

>>8767662
The opposite of the exponential function is log.
The opposite of power is root.
Example: 2^3= 8 (this is power), 3rd root of 8 is 2.
e^3 = 20.08. log(20.08)=3.
Now the real question is: what is e?

>>8767709
(x^2)*(x^1/2)=x
That's all root is.

>>8767765
But... Thats wrong

>>8767765

>>8767765

lmao

>>8766209

I don't think functions can have sexuality

but he's not talking about the inverse of the factorial function just the inverse of the operation, which I suppose would just be the factorial operation itself. multiplication and division are fundamentally the same thing, aren't they?

>>8767765
[math]x^2 \cdot \sqrt{x} = x^{2.5} \neq x [/math]

>>8766206
1 / [b]factorial[/b] ?

>>8767788
Actually, that would be a number smaller than 1.
It's ( factorial(N) / (factorial(N))/log(factorial(N))) = N

>>8767807
that was bait.
Also, good job rendering your expression meaningless by not having enough parenthesis.
( factorial(5) / (factorial(5))/log(factorial(5))) = 5
( 120 / (120)/log120) = 5
( 120 / 120/4.787...) = 5
( 120 / 25.065...) = 5 or ( 1/4.787...) = 5
4.787... = 5 or ( 0.209...) = 5

>>8767771
I meant x^(2*1/2)=x

>>8767777
>he's not talking about the inverse of the factorial function just the inverse of the operation
what did he mean by this
