the measurement of an acute angle in a triangle with a right angle, that is calculated by dividing the length of the side next to it by the length of the hypotenuse sine (cosinus, from co- + sinus ( SINE))
Cos(q) is the x-coordinate of the point on the unit circle so that the ray connecting the point with the origin makes an angle of q with the positive x-axis When q is an angle of a right triangle, then COs(q) is the ratio of the adjacent side with the hypotenuse

Generalization of the Pythagorean theorem relating the lengths of the sides of any triangle. If a, b, and c are the lengths of the sides and C is the angle opposite side c, then c^2 = a^2 + b^2 -2ab cos C
