Calculus is the part of mathematics which deals with the ratio of change of quantities.Pre-calculus is one of the two kinds of Calculus.Precalculus is static and calculus is changing.Pre-calculus deals with slope of a line and the rate of speed of a moving object.The slope of a curve and the rate of speed of an object are dealt with by calculus.

If you take is isA physicist will try to calculate the rate of change in the object's speed.The chemist handles the rate of change from one substance to another.The biologist deals with the change in population of a species over time.Over some time the economist deals with the rate of change of the share price.

Learning calculus is important for students because it can be used in any of the professional careers they would be taking over in their life.The calculus was introduced in Germany and England at the same time.After becoming an expert in mathematics Newton spent his time inventing new concepts related to the rate of change which is credited with creating the differential calculus.The birth of Calculus occurred because of this.There is a debate about who first discovered math.

One of the major mathematicians who contributed is Louis Cauchy.The definition of a limit and formula for the limits of difference quotients was created by him.The mathematician who contributed to calculus is Karl Weierstrass.He gives the concepts of limits differentiability and continuity.Pre-calculus methods are able to calculate the tangent to a circle.

We can use pre-calculus methods to analyse the area of a square but we need to use the methods for the curve.The three stages of Calculus are shown in theThe first step is the pre-calculus followed by the limit process and finally the calculus.It is not wise for students to learn a set of formulas without knowing the definition.The concept of limit was devised by Louis and Karl in the 19th century even though calculus has been around for 1000s of years.
