The part of mathematics that deals with the change of quantities is called Calculus.A pre-calculus is one of the two types of calculus.Precalculus is static and the other is dynamic.Pre-calculus deals with the slope and speed of an object.The slope of a curve and the rate of speed of a changing object are deals with by calculus.

If you take is isThe physicist deals with the object's velocity and tries to calculate the rate of change.The chemist keeps track of the rate of change between substances.The rate of population change of a species is deals with by a Biologist.Over a period of time the economist deals with the rate of change of the share price and economic index.

It is important for students to learn calculus as it has applicability in any of the professional careers they would be taking over in their lives.Two people from Germany and England introduced the same thing.After becoming an expert in mathematics Newton spent his time inventing new concepts related to the rate of change which is the credit for creation of the differential calculus.This caused the birth of Calculus.There is a disagreement about who was the first to discover something.

Cauchy is a mathematician and a major contributor.The formula for the limits of difference quotients was created by the mathematician.Karl Weierstrass is a mathematician a major one.Limits differentiability and continuity are some of the concepts that he gave as a mathematician.We can use pre-calculus methods to figure out the angle to the circle.

We can use pre-calculus methods to analyse the area of a square but we need to use thecalculus methods to analyse the curve under it.There are three stages inculus.The beginning of the process is pre-calculus followed by the limit process and finally the calculus.It is not a good idea for students to learn a set of formulas without knowing what they are.The concept of limit was created only in the 19th century by Louis and Karl despite the fact that calculus is around for 1000s of years.
