kääntymiskulmien
Kääntymiskulmien, a Finnish term, translates to "turning angles" or "angles of rotation" in English. This concept is fundamental in geometry and various fields of mathematics, particularly in trigonometry and vector analysis. It refers to the measure of an angle formed by rotating a ray originating from a common initial point, called the vertex, around that point. The rotation can be either counterclockwise, typically considered positive, or clockwise, usually considered negative.
In trigonometry, kääntymiskulmien are used to define trigonometric functions such as sine, cosine, and tangent. These
Beyond trigonometry, kääntymiskulmien play a role in describing the orientation of objects in space, such as
