how much is dy/dx with respect to x?

It is entirely defined by what y is.

>>8591805
About as long as a piece of string.

>>8591816
what is y?

>>8591847
The shit you're applying d/dx to.

>>8591805
You should pay atention in class.
dy/dx (a) = lim (y(a+h)-y(a)) / h

>>8591864
or dy/dx (a) = lim (y(a)-y(x))/(a-x)
1st limit is when h->0
2nd limit when x->a

bout tree fiddy

>>8591858
what is d/dx? isnt that just (dy/dx)*(1/y)?

>>8591864
>>8591866
that doesn't even make sense
where did a and h come from? what is ->? why use limits?

>>8591911
d/dx means derivative w.r.t. x

>>8591915

-> means tending to.
So h is tending to 0

>>8591915
It's an operation. Horrible notation, at that. Try Lagrangian.

could you explain that in simpler way?
I just finished high school and I'm trying to do my preliminary work for economy college but this shit is really confusing

Dy/dx means the derivative of y with respect to x. What the fuck is a derivative of y with respect to x with respect to x?
