Archi Associati e Riduzione al Primo Quadrante

Explanation with examples of associated arcs and reduction to the first quadrant. Let's see how to derive the formulas for associated arcs, how to use them, and some calculation examples. In trigonometry and trigonometry, recognizing associated arcs/angles is useful because it allows you to derive the values ​​of the sine and cosine functions of angles in the second, third, and fourth quadrants by memorizing the values ​​of the corresponding arcs/angle in the first quadrant.
