# Trigonometry

This is one of the most important branch of mathematics dealing with the study of lines, angles and shapes. Trigonometry deals with the study of sides and angles of right angle triangle. Different types of concepts like functions, ratios and formulas will be covered in this course. By the end of this course you will be to identify missing angles and sides of the right angle triangles. The terms that are used to express angles in trigonometry are degrees and radians.

## Important Functions of Trigonometry

Sine

Tangent

Cosine

Cosecant

Secant

Cotangent

Some of the more important functions that will be under consideration in this course are as follow:

• Even and odd Trigonometric Functions

• Trigonometric angles

• Unit Circles

• Trigonometric Formulas

• Trigonometric Identities

## Important Trigonometry Lessons

Some of the more important lessons that will be covered in this course are as follow:

• Triangle Classification theorem.

• Angles and Trigonometric Functions.

• Trigonometric Equations

• Applying Vectors

• Hyperbola Equations

## Goals of the Course

After completion of the course the students will reach at a certain satisfaction level. Some of the goals that we have marked are as follow:

• The students will be able to define trigonometry and what are the different functions of trigonometry.

• The students will be able to identify different angles which were unknown to them before.

• Representation of equations and graphs.

• Understand right angle triangle and solve different types of problems with it.

• Understanding of polar and complex coordinate systems.

## Applications of Trigonometry

Below are some of the fields in which trigonometry is widely used.
