Trigonometry Ratio Table- sin cos tan Table

Trigonometric ratios are included in the trigonometric table: sine, cosine, tangent, cosecant, secant, and cotangent. These ratios are abbreviated as sin, cos, tan, cosec, sec, and cot.  The Fast Fourier Transform algorithms are another notable application of trigonometric tables. In solving trigonometry issues, the values of trigonometric ratios of standard angles in a Trigonometry Table are useful. In this article, we will discuss the tricks to create the Trigonometry Table.

Trigonometry Table (0°-360°) Preparation Trick for Class 10 and 12

We can easily create a Trigonometry Table by using the following steps-

Step 1: Make a table with the top row listing the angles such as 0°, 30°, 45°, 60°, 90°, and the first column containing the trigonometric functions such as sin, , cosec, cos, tan, cot, sec. 

Step 2: calculating the value of sin for different angles: In ascending order, write the angles 0°, 30°, 45°, 60°, and 90° and assign them the numbers 0, 1, 2, 3, 4 according to the order. As a result, 0 will be assigned to 0°; 1 will be assigned to 30°; 2 will be assigned to 45°; 3 will be assigned to  60°; 4 will be assigned to 90°. Next, divide the values by four and square root the total value. 

 0° ⟶ √(0/4) = 0

30° ⟶ √(1 /4) = 1/2 

45° ⟶ √(2/4) = 1/ √2

60° ⟶√(3/4) = √3/2

90° ⟶ √(4/4) = 1

This offers the sine values for these 5 angles i.e. 0°, 30°, 45°, 60°, 90°. Now for the last three angles we will use the formula given below:

sin (180° − x) = sin x

sin (180° + x) = -sin x

sin (360° − x) = -sin x

Calculate the values of 180º, 270º, 360º   

sin (180° − 0º) = sin 0º 

Here we are taking x = 0 because we have to find the value of Sin 180º. Thus, putting x = 0º  is satisfying the formula. 

sin (180° + 90º) = -sin 90º

Here we are taking x = 90º because we have to find the value of Sin 270º. Thus, putting x = 90º  is satisfying the formula.  

sin (360° − 0º) = -sin 0º

Here we are taking x = 0º because we have to find the value of Sin 360º. Thus, putting x = 0º  is satisfying the formula.

30° 45° 60° 90° 180° 270° 360°
sin 0 1/2 1/√2 √3/2 1 0 -1 0

 

Step 3: To find the value of cos, use the formula sin (90° – x) = cos x. Use this formula to calculate cos x for all the angles. 

Example: 

for value of X =  0°

Cos 0° = sin (90° – 0°) = sin 90°

for value of X =  30°

cos 30° = sin (90° – 30°) = sin 60°.

for value of X =  45°

Cos 45° = sin (90° – 45°) = sin 45°

for value of X =  60°

cos 60° = sin (90° – 60°) = sin 30°

for value of X =  90°

cos 90° = sin (90° – 90°) = sin 0°

for value of X =  180°

cos 180° = sin (90° – 180°) = -sin 90°

for value of X =  270°

cos 270° = sin (90° – 270°) = -sin 180°

for value of X =  360°

cos 360° = sin (90° – 360°) = -sin 270°

Step 4: Calculate the value of tan for all the angles. Use the formula given below: 

 tan x = sin x/cos x

Calculate the value of tan by putting all the angles in the formula given above.

Angles (In Degrees) 30° 45° 60° 90° 180° 270° 360°
tan 0 1/√3 1 √3 0 0

cot x = 1/tan x

Calculate the value of the cot by putting all the angles in the formula given above.

Angles (In Degrees) 30° 45° 60° 90° 180° 270° 360°
cot √3 1 1/√3 0 0

 

Step 6: Calculate the value of cosec for all the angles. Use the formula given below: 

cosec x = 1/sin x

Calculate the value of cosec by putting all the angles in the formula given above.

Angles (In Degrees) 30° 45° 60° 90° 180° 270° 360°
cosec 2 √2 2/√3 1 -1

 

Step 7: Calculate the value of sec for all the angles. Use the formula given below: 

sec x = 1/cos x

Calculate the value of sec by putting all the angles in the formula given above.

Angles (In Degrees) 30° 45° 60° 90° 180° 270° 360°
sec 1 2/√3 √2 2 -1 1

Trigonometric Table (0°-360°) Examples

Q.Find the Exact value of Sin 15 using trigonometry table values.

Answer-  sin15 ° can be written as, sin(45° -30°)

sin15°= sin(45° -30°)= sin45° cos30°-cos45°sin30°,

[using formula sin(X-Y)=sinXcosY-cosXsinY] 

or,sin15° = (1/√2 ×√3/2)- (1/2×1/√2)  { using Trigonometery Table values }

sin15° = 1/√2 [(√3 -1)/2]

sin15° = (√3 -1)/2√2 (Answer)

Q. If θ =30°,prove that  cos 2θ =cos²θ -sin² θ

Answer- θ =30°

R.H.S –  cos²θ – sin² θ

= cos²30° – sin²30° = (1/2 )² – (√3/2 )² =3/4 – 1/4 = 1/2 

L.H.S – cos 2θ 

= cos 2 ( 30° )= Cos 60° = !/2 

Hence, L.H.S =R.H.S [ Proved]

Q.Find the length of the ladder which is leaning against a wall with an angle of 60° and the foot of the ladder is 12.4 m away from the wall.

Answer-  In the above question, the length of the base is 12.4 m. The elevation angle is 60°.

Now, let’s assume the length of the ladder is h m

Cos 60°= 12.4/ h

or,1/2 = 12.4/h

or, h = 2 ×12.4 = 24.8 m.

Hence, the length of the ladder is 24.8 m.
