In order to find the value of a trigonometric function using the sine, cosine, tangent, and cotangent table, pick the relevant function and the degree (or radian) value in the table. Then, find the intersection of the selected parameters.

If you need a value of a trigonometric function that is not in the table, you can use either the Bradis Table or transformations that help reduce the quantity to the table value.

 

The tables of values of sine, cosine, tangent, and cotangent can be represented in two ways.

 

You can choose the table based on preference.

1st method. The trigonometric functions are placed in rows, and the values of their angles (in degrees and radians) are in columns

2nd method. The trigonometric functions are placed in columns, and the values of their angles (in degrees and radians) are in rows
