**dy**means change in y in a function, just as dx represents the change in x.**dy**/dx refers to the change in slope on a function, being rise over run.**dy**and dx are (usually) solvable variables, when intervals are set.Who came up with dy dx?

A competing notation was invented by Newton's rival

**Leibnitz**. If y is a function of x,**Leibnitz**represents the derivative by dy/dx instead of our y'. This notation has advantages and disadvantages.What is the differentiation maths?

The Definition of

**Differentiation**. The essence of calculus is the derivative. The derivative is the instantaneous rate of change of a function with respect to one of its variables. This is equivalent to finding the slope of the tangent line to the function at a point.
