Sine is the ratio of the Opposite Side / Hypotenuse of a right triangle, so in a right triangle from the position of an angle of 60 degrees, the length of the Opposite side is .866025 as long as the hypotenuse. As with {{mIRC|$calc|$calc()}}, the returned fraction is limited to 6 decimal places. | Sine is the ratio of the Opposite Side / Hypotenuse of a right triangle, so in a right triangle from the position of an angle of 60 degrees, the length of the Opposite side is .866025 as long as the hypotenuse.

$sin 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. | $sin accepts numbers larger than 1 rotation of a circle, as if the angle loops past the origin and continues.
