Calculus is the part of mathematics that deals with the ratio of changes of quantities.Pre-calculus is one of the types of calculus.Precalculus is mostly static and dynamic.Pre-calculus deals with the slope of a line and the speed of an object that is moving.The slope of a curve and the rate of speed are deals with in calculus.

If you take isThe physicist tries to calculate the rate of change in velocity when they deal with the object.The chemist deals with the rate of change between substances.The rate at which the population of a species changes over time is dealt with by a Biologist.Over a period of time the economist deals with the rate of change of the share price.

Calculus is important for students because it can be used in any of the professional careers they would be taking over in their life.It was introduced by two people around the same time one from England and the other from Germany.The differential calculus was created byNewton who after becoming an expert in mathematics invented new concepts related to the rate of change.The birth of Calculus happens because of this.Some people think that Leibnitz was the first to discover calculus.

He is a major mathematician.He is the first mathematician to come up with a formula for the limits of difference quotients.Another mathematician is Karl Weierstrass.Limits differentiability and continuity are some of the concepts given to him by a german mathematician.Pre-calculus can be used to calculate the tangent to a circle.

Pre-calculus methods can be used to analyse the area of a square but under a curve pre-calculus methods are needed.The three stages of calculus are shown in theThe first part is pre-calculus the second part is the limit process and the third part is the calculus.It's not a good idea for students to learn calculus as a set of formulas if they don't know the definition.The concept of limit was created by Karl and Louis in the 19th century.
