I don't get the concept of the notation dy/dx. Sometimes my physics teacher puts dx in the back of an equation and cross multiply with other number. Does this mean dx can be multiply like numbers? I just don't get the overall concept of dy/dx.
I'm in 3rd year calculus and I understand that derivative is the instantaneous rate of change but how does it relates to the notation?
