Table of cosine values of the cosines of the angles recorded in the table from 0° to 360°.
Using a table of cosines you can calculate even if not at hand will be the scientific calculator.
To find the cosine of the desired angle, it is sufficient to use the table.

Table of cosine - narovne a table of sines is studied in the beginning of trigonometry. Without an understanding of the table of cosines it will be very difficult to study trigonometry and to apply trigonometric formulas.
Trigonometric functions are of great practical importance in geometry. Is in fact only indicators of the relationship of various sides of a right triangle to each other, they can help in solving most problems, the result of which is reduced to solutions of right triangles.
One of the main trigonometric functions is the cosine. Therefore, in this table of cosines you can find any value of cosine.
