Cosine(30) = sqrt(3)/2
Cosine cannot have this kind of high value, it ranges from -1 to +1
It doesn't exist. The maximum value of the cosine is 1.00, so no angle can have a cosine of (pi), because (pi) is more than 3.
The cosine of 20 degrees is 0.93969262
It is exactly 79.
Looking at a unit circle, cosine is the horizontal coordinate. Pi radians is halfway around the circle (180°), so the coordinate is (-1,0). Cosine(pi) = -1
It is 0.9849
The cosine of 70 degrees is 0.34202014332567.
In degrees they are the same value.
