Trigonometric functions are also known as Circular Functions can be simply defined as the functions of an angle of a triangle. It means that the relationship between the angles and sides of a triangle are given by these trig functions. The basic trigonometric functions are sine, cosine, tangent, cotangent, secant and cosecant. Also, read trigonometric identities here. Table of Contents: Basic Trigonometric Functions Sine Cosine Tangent Cotangent, Secant, Cosecant Formulas Identities Table Graphs Examples There are a number of trigonometric formulas and identities that denotes the relation between the functions and help to find the angles of the triangle. All these trigonometric functions with their formula are explained here elaborately, to make them understand to the readers. Also, you will come across the table where the value of these ratios is mentioned for some particular degrees. And based on this table you will be able to solve many trigonometric examples and problems. Six Trigonometric Functions The angles of sine, cosine, and tangent are the primary classification of functions of trigonometry. And the three functions which are cotangent, secant and cosecant can be derived from the primary functions. Basically, the other three functions are often used as compared to the primary trigonometric functions. Consider the following diagram as a reference for an explanation of these three primary functions. This diagram can be referred to as the sin-cos-tan triangle. We usually define trigonometry with the help of the right-angled triangle. Trigonometric Functions Sine Function Sine function of an angle is the ratio between the opposite side length to that of the hypotenuse. From the above diagram, the value of sin will be: Sin a =Opposite/Hypotenuse = CB/CA Cos Function Cos of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse. From the above diagram, the cos function will be derived as follows. Cos a = Adjacent/Hypotenuse = AB/CA Tan Function The tangent function is the ratio of the length of the opposite side to that of the adjacent side. It should be noted that the tan can also be represented in terms of sine and cos as their ratio. From the diagram taken above, the tan function will be the following. Tan a = Opposite/Adjacent = CB/BA Also, in terms of sine and cos, tan can be represented as: Tan a = sin a/cos a Secant, Cosecant and Cotangent Functions Secant, cosecant (csc) and cotangent are the three additional functions which are derived from the primary functions of sine, cos, and tan. The reciprocal of sine, cos, and tan are cosecant (csc), secant (sec), and cotangent (cot) respectively. The formula of each of these functions are given as: Sec a = 1/(cos a) = Hypotenuse/Adjacent = CA/AB Cosec a = 1/(sin a) = Hypotenuse/Opposite = CA/CB cot a = 1/(tan a) = Adjacent/Opposite = BA/CB Note: Inverse trigonometric functions are used to obtain an angle from any of the angle’s trigonometric ratios. Basically, inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions are represented as arcsine, arccosine, arctangent, arc cotangent, arc secant, and arc cosecant. Formulas Let us discuss the formulas given in the table below for functions of trigonometric ratios(sine, cosine, tangent, cotangent, secant and cosecant) for a right-angled triangle. Formulas for Angle θ Reciprocal Identities sin θ = Opposite Side/Hypotenuse sin θ = 1/cosec θ cos θ = Adjacent Side/Hypotenuse cos θ = 1/sec θ tan θ = Opposite Side/Adjacent tan θ = 1/cot θ cot θ = Adjacent Side/Opposite cot θ = 1/tan θ sec θ = Hypotenuse/Adjacent Side sec θ = 1/cos θ cosec θ = Hypotenuse/Opposite cosec θ = 1/sin θ Identities Below are the identities related to trig functions. Even and Odd functions The cos and sec functions are even functions; the rest other functions are odd functions. sin(-x) = -sin x cos(-x) = cos x tan(-x) = - tan x cot(-x) = -cot x csc(-x) = -csc x sec(-x) = sec x Periodic Functions The trig functions are the periodic functions. The smallest periodic cycle is 2π but for tangent and the cotangent it is π. sin(x+2nπ) = sin x cos(x+2nπ) = cos x tan(x+nπ) = tan x cot(x+nπ) = cot x csc(x+2nπ) = csc x sec(x+2nπ) = sec x Where n is any integer. Pythagorean Identities When the Pythagoras theorem is expressed in the form of trigonometry functions, it is said to be Pythagorean identity. There are majorly three identities: sin2 x + cos2 x = 1 [Very Important] 1+tan2 x = sec2 x cosec2 x = 1 + cot2 x These three identities are of great importance in Mathematics, as most of the trigonometry questions are prepared in exams based on them.

Solution: Sin 105° can be written as sin (60° + 45°) which is similar to sin (A + B). We know that, the formula for sin (A + B) = sin A × cos B + cos A × sin B Therefore, sin 105° = sin (60° + 45°) = sin 60° × cos 45° + cos 60° × sin 45° = √3/2 × 1/√2 + 1/2 × 1/√2 = √3/2√2 + 1/2√2 = (√3+1)/2√2 Example 3: A boy sees a bird sitting on a tree at an angle of elevation of 20°. If a boy is standing 10 miles away from the tree, at what height bird is sitting? Solution: Consider ABC a right triangle, A is a bird’s location, B = tree is touching the ground and C = boy’s location. So BC 10 miles, angle C = 20° and let AB = x miles We know, tan C = opposite side/adjacent side tan(20°) = x/10 or x = 10 × tan(20°) or x = 10 × 0.36 = 3.6 Bird is sitting at the height of 3.6 miles from the ground.

To convert degrees to radians, you can use the formula: \[ \text{radians} = \text{degrees} \times \frac{\pi}{180} \] For a 60-degree angle: \[ 60 \times \frac{\pi}{180} = \frac{\pi}{3} \] So, 60 degrees is \(\frac{\pi}{3}\) radians. Like the comment please 🖐🖐❤❤

60° in radian = 360°=2pie
Divided by 6 both side
360°/6=2pie/6
60°=pie/3
or you can do it in this way too
pi = 180 degree
180/3 = 60 degree (divide on both sides)
therefore pi/3 = 60 degree

The angles of sine, cosine, and tangent are the primary classification of functions of trigonometry. And the three functions which are cotangent, secant and cosecant can be derived from the primary functions. Basically, the other three functions are often used as compared to the primary trigonometric functions. Consider the following diagram as a reference for an explanation of these three primary functions. This diagram can be referred to as the sin-cos-tan triangle. We usually define trigonometry with the help of the right-angled triangle.
Trigonometric Functions
Sine Function
Sine function of an angle is the ratio between the opposite side length to that of the hypotenuse. From the above diagram, the value of sin will be:
Sin a =Opposite/Hypotenuse = CB/CA
Cos Function
Cos of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse. From the above diagram, the cos function will be derived as follows.
Cos a = Adjacent/Hypotenuse = AB/CA
Tan Function
The tangent function is the ratio of the length of the opposite side to that of the adjacent side. It should be noted that the tan can also be represented in terms of sine and cos as their ratio. From the diagram taken above, the tan function will be the following.
Tan a = Opposite/Adjacent = CB/BA
Also, in terms of sine and cos, tan can be represented as:
Tan a = sin a/cos a
Secant, Cosecant and Cotangent Functions
Secant, cosecant (csc) and cotangent are the three additional functions which are derived from the primary functions of sine, cos, and tan. The reciprocal of sine, cos, and tan are cosecant (csc), secant (sec), and cotangent (cot) respectively. The formula of each of these functions are given as:
Sec a = 1/(cos a) = Hypotenuse/Adjacent = CA/AB
Cosec a = 1/(sin a) = Hypotenuse/Opposite = CA/CB
cot a = 1/(tan a) = Adjacent/Opposite = BA/CB
Note: Inverse trigonometric functions are used to obtain an angle from any of the angle’s trigonometric ratios. Basically, inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions are represented as arcsine, arccosine, arctangent, arc cotangent, arc secant, and arc cosecant.
Formulas
Let us discuss the formulas given in the table below for functions of trigonometric ratios(sine, cosine, tangent, cotangent, secant and cosecant) for a right-angled triangle.
Formulas for Angle θ Reciprocal Identities
sin θ = Opposite Side/Hypotenuse sin θ = 1/cosec θ
cos θ = Adjacent Side/Hypotenuse cos θ = 1/sec θ
tan θ = Opposite Side/Adjacent tan θ = 1/cot θ
cot θ = Adjacent Side/Opposite cot θ = 1/tan θ
sec θ = Hypotenuse/Adjacent Side sec θ = 1/cos θ
cosec θ = Hypotenuse/Opposite cosec θ = 1/sin θ
Identities
Below are the identities related to trig functions.
Even and Odd functions
The cos and sec functions are even functions; the rest other functions are odd functions.
sin(-x) = -sin x
cos(-x) = cos x
tan(-x) = - tan x
cot(-x) = -cot x
csc(-x) = -csc x
sec(-x) = sec x
Periodic Functions
The trig functions are the periodic functions. The smallest periodic cycle is 2π but for tangent and the cotangent it is π.
sin(x+2nπ) = sin x
cos(x+2nπ) = cos x
tan(x+nπ) = tan x
cot(x+nπ) = cot x
csc(x+2nπ) = csc x
sec(x+2nπ) = sec x
Where n is any integer.
Pythagorean Identities
When the Pythagoras theorem is expressed in the form of trigonometry functions, it is said to be Pythagorean identity. There are majorly three identities:
sin2 x + cos2 x = 1 [Very Important]
1+tan2 x = sec2 x
cosec2 x = 1 + cot2 x
These three identities are of great importance in Mathematics, as most of the trigonometry questions are prepared in exams based on them. Therefore, students should memorise these identities to solve such problems easily.
Sum and Difference Identities
sin(x+y) = sin(x).cos(y)+cos(x).sin(y)
sin(x-y) = sin(x).cos(y)-cos(x).sin(y)
cos(x+y) = cosx.cosy-sinx.siny
cos(x-y) = cosx.cosy+sinx.siny
tan(x+y) = [tan(x)+tan(y)]/[1-tan(x)tan(y)]

Solved Examples on Trigonometric Functions
Example 1: Find the values of Sin 45°, Cos 60° and Tan 60°.
Solution: Using the trigonometric table, we have
Sin 45° = 1/√2
Cos 60° = 1/2
Tan 60° = √3
Example 2: Evaluate Sin 105° degrees.
Solution: Sin 105° can be written as sin (60° + 45°) which is similar to sin (A + B).
We know that, the formula for sin (A + B) = sin A × cos B + cos A × sin B
Therefore, sin 105° = sin (60° + 45°) = sin 60° × cos 45° + cos 60° × sin 45°
= √3/2 × 1/√2 + 1/2 × 1/√2
= √3/2√2 + 1/2√2
= (√3+1)/2√2
Example 3: A boy sees a bird sitting on a tree at an angle of elevation of 20°. If a boy is standing 10 miles away from the tree, at what height bird is sitting?
Solution: Consider ABC a right triangle, A is a bird’s location, B = tree is touching the ground and C = boy’s location.
So BC 10 miles, angle C = 20° and let AB = x miles
We know, tan C = opposite side/adjacent side
tan(20°) = x/10
or x = 10 × tan(20°)
or x = 10 × 0.36 = 3.6
Bird is sitting at the height of 3.6 miles from the ground.

To convert degrees to radians, you can use the formula:
\[ \text{radians} = \text{degrees} \times \frac{\pi}{180} \]
For a 60-degree angle:
\[ 60 \times \frac{\pi}{180} = \frac{\pi}{3} \]
So, 60 degrees is \(\frac{\pi}{3}\) radians.
