  • The cosine of 30 degrees is approximately 0.866, which means the ratio of the adjacent side to the hypotenuse is 0.866.
  • At its core, the cosine graph is a mathematical function that describes the relationship between an angle and the ratio of the adjacent side to the hypotenuse in a right-angled triangle. In essence, the cosine function returns a value between -1 and 1, representing the cosine of the angle. This value can be thought of as a measure of how "squeezed" or "stretched" the angle is.
