Cosine is the ratio of the Adjacent Side / Hypotenuse of a right triangle, so in a right triangle from the position of an angle of 30 degrees, the length of the Adjacent side is .866025 as long as the hypotenuse. As with {{mIRC|$calc|$calc()}}, the returned fraction is limited to 6 decimal places. | Cosine is the ratio of the Adjacent Side / Hypotenuse of a right triangle, so in a right triangle from the position of an angle of 30 degrees, the length of the Adjacent side is .866025 as long as the hypotenuse.

$cos accepts numbers larger than 1 rotation of a circle, as if the angle loops past the origin and continues. Assuming you are using the .deg property, angles above 360 degrees return the same result of the angle modulo 360. | $cos accepts numbers larger than 1 rotation of a circle, as if the angle loops past the origin and continues.
