In this course we build a solid understanding of Trigonometric Functions - sine , cosine , tangent . All the concepts are built up logically through diagrams, and equations are explained in detail. Later we implement the concepts through solved examples. This is a very important chapter as Trigonometric functions are immensely applied in several other Mathematical Concepts.

We have a brief look at the Course Overview - different concepts which we are going to understand in this chapter.

Trigonometric Functions - Course Overview

We understand the basic concept of Degree Measure of angle.

Angles - Degree Measure

We understand the concept of Radian measure of angle.

Angles - Radian Measure

We understand the relation between radian measure and real numbers.

Relation between Radian measure and Real Numbers

We understand the relationship between radian measure and degree measure.

Relation between Radian measure & Degree Measure

We solve some examples using our knowledge of degree and radian measure.

Solved Examples

We understand the concept of Trigonometric functions.

We visually understand trigonometric functions in terms of projections, and find values of different angles.

Trigonometric Functions - Visualization

We understand for what radian measure of angle will sin x and cos x be zero.

When do we have Sin x and Cos x equal to Zero

We understand the sign of trigonometric functions in different quadrants.

Sign of Trigonometric Functions

We understand the concept of domain and range of sin, cos and cosec functions.

Domain & Range of Trigonometric Functions

We understand the domain and range of sec x, tan x and cot x. We also visualize what happens when we change the radian measure of angles.

Domain & Range of Trigonometric functions - sec, tan, cot

We understand how to plot the graph of sin x.

Graph of sin x

We visualize the trigonometric angles for 2π - x and 2π + x

Very Useful Trigonometric Identities Visualisation

We visualize the trigonometric ratios of angles π-x and π+x

Trigonometric Identities Visualisation

We derive the expression for tan(x + y) and cot (x + y)

Tan(x + y), cot(x + y) = ?

We derive the expression for sin 2x, sin 3x, cos 2x, cos 3x , tan 2x, tan 3x

Sin 2x, sin 3x, cos 2x, cos 3x, tan 2x, tan 3x = ?

We derive very important expressions for cos (x + y) + cos ( x - y), cos x + cos y, etc.

Cos (x + y) + cos (x - y) , cos x + cos y = ?

Students often start to fear about how to remember all the trigonometric formulas. In this lecture today we briefly summarise all the formulas we derived until now, and also advise students on how to remember the important trigonometric formulas.

How to remember important Trigonometric formulas ?

We solve some examples using our knowledge of Trigonometric formulas.
