it is not me meaningless...
integral of x dx = x^2/2 + Constant
[integral of x dx](x=1) = 1/2 + Constant
[integral of x dx](x=0) = 0 + Constant (same constant)
Integral of x dx, x=0 to x=1... is equal... [integral of x dx](x=1) minus [integral of x dx](x=0)
is equal
(1/2 +...
when we integrate f(x) from x=0 to x=1, the result is [the integral of f(x)] calculated with x=1 minus [the integral of f(x)] calculated with x = 0...
then... I tried to mean... integral f(x) dx from "a" to "x" is equal to [integral of f(x)](undefined) minus [integral of f(x)](undefined) with x...
micromass...ok, how should I write "Integral of f(x)dx calculated on x=a"?
micromass... I tried to find the K to the function f(x)=a Ln(b x + c) + d, and I found a K=c/b(d-a), and it is impossible to assume x=0 like you said above..
I'm thinking that the K can show the form how you could write...
Guys... I'm not a mathematician, so, sorry about my informality in math...
here is something crazy that I discovered about 2 years ago.
It is a way to discover some integrals without integrate the f(x)...
It is a way knowing the f-1(x)...
there is a crazy K (constant i guess)... I...
Hi David.. I know this topic is very OLD (about 1.5 year), but when searching on google for exactly what you want, i was delivered to this forum... with no answer... so I kept searching and I found the derivation... you can find it here:
