Kappa
i dont know m8, im not good at giving respects Kappa
You can take a partial derivative then
only partial respect
okay umbreon
I guess I am teaching you about derivatives
get ready to get mathed
do you know what a limit is?
nope
do you know what a function is
a limit is when you take a function as it approces some point
so the limit as x goes to 3 of x^2 is 8
uh sure Kappa
because
as x goes to 3
3^2 is 8
anyways, a derivitve is defines as this
i see
this is also the definition of the slop of the line f(x)
basically, say you have f(x)= x-4 to be easy
so the top is (x+h-4) - (x-4)
which is just h
h/h is 1
so the slope of the line x-4 is 1
now, for something more difficult, such as x^2, you have
f(x+h)=x^2+2xh+h^2
so the top is x^2 + 2xh + h^2 -x^2
or 2xh + h^2
I JUST REALIZED
It should not be x -> h
it should be h -> 0
I am a bad teacher
alright so forget everything
Kappa
what I said is still valid fuck you
anyways
the thing is not the lim as h->0 of 2x + h
which is 2x
since h becomes 0
so the slope of the curve x^2 is 2x
so at x=5, for example, the slope of the curve is 10
this is what a derivative is
the integral, which I started this out by showing you, is basically undoing that
it basically goes from 2x to x^2
There you go umbreon
I just expanded your math knowledge
now solve my problem you shit Kappa
sounds like a shit show
Kappa
well first you have to square both sides of the expression
Kappa
what is the last thing you learned
math wise
other than from me
logs and ln
so then
the derivative of lnx is 1/x
Kappa
i see where you're coming from Kappa
I mean
so first you have to square both sides
Keepo
and then you multiply by x^5 (9x-1)^1/2
and then you solve for x Kappa
Do you know the binomail expansion?
what the fuck
