60 degrees = 0.5 1/2
It is 1.
As a decimal: 0.866 As a fraction: √(3)/2
Cosine (0) = 1 Sin(0) = 0 The sine and cosine curves are two intertwining curves, that complement each other, hence the words 'Sine (Curve) and Cosine ( COmplementary Curve).
-1<cosine<1
Cosine of 1 degree is about 0.999848. Cosine of 1 radian is about 0.540302.
