The cosine of 90 degrees is zero.
0.5877852523
0.965925826
Cosine(30) = sqrt(3)/2
Cosine cannot have this kind of high value, it ranges from -1 to +1
Cosine of -90 is 0.
The cosine of 90 degrees is zero.
Cosine of 90 degrees is zero.
cosine (90- theta) = sine (theta)
The Unit Circle is a circle that has a radius of 1 and a center at the origin. If you look at the unit circle 90 degrees is at the point (0,1). Cosine is equal to the x value of a point on the Unit Circle. The line created to the point (0,1) on the unit circle when the degree is 90 is completely vertical, which in turn makes the x value 0 and thus, cosine of 90 = 0.

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
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
