Cos(57 deg) = 0.5446 approx.
Cos(30) = sqrt(3)/2 = 0.866025403.... ( Which is irrational).
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
The Y-Intercept of the cosine function is X = 0, Y = cosine(0) = 1.
