I do not understand the difference between taking the derivative, and taking the derivative with respect to x, or taking the derivative with respect to y (or any other variable).
If I take the derivative of y = x^2, I get y' = 2x. What if I use the dy/dx or just the d/dx notation?
so
dy/dx y = dy/dx x^2
vs
d/dx y = d/dx x^2
another example I don't understand would be
dy/dx = 2x
vs
d/dx = 2x
vs
f'(x) = 2x
I know that the d refers to an infinitesimally small number, but I just don't understand the difference between the stuff I mentioned before.
Someone enlighten me?
