There is a part of mathematics that deals with the ratio of change of quantities.Pre-calculus is a type of calculus.Precalculus can be static or dynamic.The slope of a line and the rate of speed of an object are dealt with in pre-calculus.The slope of a curve and the speed of an object are dealt with in calculus.

If you take isThe physicist tries to calculate the rate of change in the object'svelocity.The chemist deals with change from one substance to another.The biologist deals with how the population of a species changes over time.The rate of change of the share price is one of the topics that the economist deals with.

It's important for students to learn calculus as it has applicability in any of the professional careers they would be taking over in their life.Two people from Germany and England introduced the calculus around the same time.After becoming an expert in mathematics Newton spent his time inventing new concepts related to the rate of change which is how the differential calculus was created.The birth of Calculus can be attributed to this.There is a dispute about who discovered what.

Cauchy is a major mathematician.He created the formula for the limits of difference quotients and created the definition of a limit.Karl Weierstrass is a mathematician who contributed to calculus.The german mathematician gave the concepts of limits differentiability and continuity.Pre-calculus methods can be used to calculate 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.There are three stages in calculus.The first part is pre-calculus and the second part is limit process.It's not advisable for students to learn calculus if they don't know the definition.The concept of limit was created by Louis and Karl only in the 19th century.
