Hello all~
I really was curious as to why dy/dx can be treated as a fraction when solving equations, and not an operator. For example why can
dy/dx = x be the same as dy = xdx?
My second question was what EXACTLY does dx (any variable, I'll just call it x) mean by itself?
Finally, why is indefinite integral notation written (integral sign) f(x) dx? What is the significance of the dx?
Thanks
