And Using These Data Only The First Mechanical Computing Device Was Discovered. Hence These Values Are Very Important And You Must By Heart Them.
Steps To Create A Trigonometry Table
Step 1 :
Create a table with the top row listing the angles such as 0°, 30°, 45°, 60°, 90°, and write all trigonometric functions in the first column such as sin, cos, tan, cosec, sec, cot.
Step 2 : Determine The Value Of Sin
To determine the values of sin, divide 0, 1, 2, 3, 4 by 4 under the root, respectively. See the example below.
To determine the value of sin 0°04=0
| Angles (In Degrees) | 0° | 30° | 45° | 60° | 90° | 180° | 270° | 360° |
| sin | 0 | 1/2 | 1/√2 | √3/2 | 1 | 0 | -1 | 0 |
Step 3 : Determine The Value Of Cos
The cos-value is the opposite angle of the sin angle. To determine the value of cos divide by 4 in the opposite sequence of sin. For example, divide 4 by 4 under the root to get the value of cos 0°. See the example below.
To determine the value of cos 0°44=1
| Angles (In Degrees) | 0° | 30° | 45° | 60° | 90° | 180° | 270° | 360° |
| cos | 1 | √3/2 | 1/√2 | 1/2 | 0 | -1 | 0 | 1 |
Step 4 : Determine The Value Of Tan
The tan is equal to sin divided by cos. tan = sin/cos. To determine the value of tan at 0° divide the value of sin at 0° by the value of cos at 0°. See the example below.
tan 0°= 0/1 = 0
Similarly, the table would be.
| Angles (In Degrees) | 0° | 30° | 45° | 60° | 90° | 180° | 270° | 360° |
| tan | 0 | 1/√3 | 1 | √3 | ∞ | 0 | ∞ | 0 |
Step 5 : Determine The Value Of Cot
The value of cot is equal to the reciprocal of tan. The value of cot at 0° will obtain by dividing 1 by the value of tan at 0°. So the value will be:
cot 0° = 1/0 = Infinite or Not Defined
Same way, the table for a cot is given below.
| Angles (In Degrees) | 0° | 30° | 45° | 60° | 90° | 180° | 270° | 360° |
| cot | ∞ | √3 | 1 | 1/√3 | 0 | ∞ | 0 | ∞ |
Step 6 : Determine The Value Of Cosec
The value of cosec at 0° is the reciprocal of sin at 0°.
cosec 0°= 1/0 = Infinite or Not Defined
Same way, the table for cosec is given below.
| Angles (In Degrees) | 0° | 30° | 45° | 60° | 90° | 180° | 270° | 360° |
| cosec | ∞ | 2 | √2 | 2/√3 | 1 | ∞ | -1 | ∞ |
Step 7 : Determine The Value Of Sec
The value of sec can be determined by all reciprocal values of cos. The value of sec on 0° is the opposite of cos on 0°. So the value will be:sec0∘=11=1
In the same way, the table for sec is given below.
| Angles (In Degrees) | 0° | 30° | 45° | 60° | 90° | 180° | 270° | 360° |
| sec | 1 | 2/√3 | √2 | 2 | ∞ | -1 | ∞ | 1 |
