Calculus is the part of mathematics where the ratio of change of quantities is dealt with.Pre-calculus is the type of calculus that is used.Precalculus is almost static.Pre-calculus deals with the slope of a line and the rate of speed of a constantly moving object.The slope of a curve and the rate of speed of an object are dealt with in the book.

If you takesThe physicist tries to calculate the rate of change in velocity by dealing with the object.The chemist changes the rate of change from one substance to another.The biologist deals with the rate of change of population of a species over time.The rate of change of the share price is a topic that the economist deals with over time.

As it has applicability in any of the professional careers that students would be taking over in their life learning calculus is very important for students.The introduction of the calculus was done by two people in the same year.After becoming an expert in mathematics Newton spent his time inventing new ideas related to the rate of change for the differential calculus.This leads to the birth of calculus.There is a conflict over who was the first to discover something.

Louis Cauchy is a mathematician and a major contributor to math.He created a formula for the limits of difference quotients and was the first mathematician to do so.Karl Weierstrass is a mathematician a major mathematician.The german mathematician gave the idea of limits differentiability and continuity.Pre-calculus methods can be used to calculate the inverse of the tangent to a circle.

We can use pre-calculus methods if we want to analyse the area of a square but if we want to analyse the area under a curve we need to use the calculus methods.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 advisable for students to learn a set of formulas if they don't know what they're talking about.The concept of limit was devised in the 19th century by Louis and Karl despite the fact that calculus is around for 1000s of years.
