# What does precalculus mean? Explain.

Calculus is a very important branch of mathematics. It finds its applications in various disciplines, especially that of engineering and science. Calculus mainly includes two concepts: Differentiation and Integration. But before studying calculus, there are various concepts that must be clear which are known as precalculus. Let's understand them in detail.

## Answer: Precalculus is the study of the mathematical prerequisites for calculus, including algebra, trigonometry and geometry.

Let's understand them in detail.

**Explanation:**

Some topics need to be understood before studying calculus known as pre calculus and they are as follows:

- Trigonometry: Trigonometry is the study of the relationships between the angles and sides of triangles. The concepts related to it are very important in calculus since they are used quite extensively. The trigonometric ratios are very widely used.
- Algebra: This deals with the equations of various degrees and multiple unknown variables, like quadratic, cubic etc. These can also be considered the backbone of calculus.
- Geometry: This branch deals with various shapes and curves and their equations in the cartesian plane. The concepts related to it are also used in calculus, especially in integration, where we find the area below a curve.
