Understanding cosine
Cosine is the horizontal coordinate of a point on the unit circle at a given angle. This calculator uses radians.
To convert degrees to radians, multiply the angle by π / 180. Cosine values lie between −1 and 1. The result is rounded to 12 decimal places; very large angles are subject to floating-point precision.
