can you make an equation in which all variables will cancle, but of which one can find the deriviative?
i haven't learned integrals (anit-derivatives) yet, but are they any use here?
it's a bit complex what i'm looking for here, so just show anything you find.
If all the variables cancel, you do not have an equation, only a statement. yx=yx is not an equation because there is no parameters for the variables to fall into, an so belong to an endless set, and so one cannot find the derivative for the equation as the derivative is a rate of change for a varible. No parameters = no definition of the varibles change.
