WHAT IS THE USE OF IT? AND WHO CREATED IT?

Reem Wathik

As we already know from the past years, algebra, geometry, & trigonometry are branches of the great Mathematics. Algebra is the study of operations and their applications to solving equations, geometry is the study of shapes, and trigonometry is the study of triangles. A fourth new branch that I will introduce you to is called, calculus, the mathematical study of change. The word calculus means ‘pebbles’ in Latin, as Pythagoreans used pebbles, lined up from different shapes, to represent numbers. People argued about who was the one who invented it first, whether is it Isaac Newton or Gottfried Leibniz, but basically all you need to know that they invented it at the same time.

Calculus has two major branches; one is the differential calculus _or derivatives_ (rates of change and slopes of function), and the other is integral calculus _or integrals_ (let you find area). These two branches are inverse concepts of each other which are related to one another by the so called fundamental theorem of calculus. Yes you do need calculus as it has widespread uses in science, economics, and engineering and can solve many problems that algebra alone cannot.

Most Important uses of calculus:

1- Predict the future: if you know the current temperature and the pressure around the world, you can solve some complicated equations and predict the temperature for the next days or even years.

2- Develop a mathematical model before trying a billion dollars experiment:

A few of decade ago when they wanted to design a new aircraft, what they’d do is design different shapes of each part and they’d see what is the most efficient and that was extremely expensive, while nowadays they’d go on the computers and design the airplane and they just try out tens of them & that’d save them millions.

3- Perform unethical or impossible experiments:

If you took a slice of your eye, you’d find some tissues there without...
