A trigonometric table is a comprehensive compilation of values for sine, cosine, tangent, and other essential trigonometric functions, typically listed at specific angle increments. Trigonometric Table Class 10
From the table below you can observe that as angle A increases from 0° to 90°, sin A increases from 0 to 1 and cos A decreases from 1 to 0.
Relation between degree and radian
The relation between degree measures and radian measure of some common angles are given in the following table:
Earlier, we have discussed the values of trigonometric ratios for 0°, 30°, 45°, 60° and 90°. The values of trigonometric functions for these angles are same
as that of trigonometric ratios studied in earlier classes. Thus, we have the following table:

The Components of a Trigonometry Table
Trigonometry tables typically include the following columns:
- Angles: Listed in degrees and sometimes radians, this column shows the angle increments, commonly ranging from 0° to 360°.
- Sine (sin): Shows the sine value for each angle, which is the ratio of the length of the opposite side to the hypotenuse in a right triangle.
- Cosine (cos): Lists the cosine values, the ratio of the adjacent side to the hypotenuse.
- Tangent (tan): Displays the tangent values, which is the ratio of the opposite side to the adjacent side.
- Cotangent (cot), Secant (sec), and Cosecant (csc): Some tables also include these additional functions, which are the reciprocals of tangen
