This can be done on a graphing calculator by making sure you have your calculator in degrees mode, and then tentering the cos(23). You get an answer of 0.9205048535.
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.
The cosine of 0.57 degrees is 0.999951. The cosine of 0.57 radians is 0.841901
It is cosine*cosine*cosine.

what is the cosine of 3.14 ?
Cosine of 1 degree is about 0.999848. Cosine of 1 radian is about 0.540302.
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
Cosine is 0.995
The inverse of the cosine is the secant.
Reciprocal of Cosine is Secant
Cosine of -90 is 0.
Cosine is a trigonometrical function.
Cosine is 0.766
You mean, you have the cosine, and want the angle? That is called arc-cosine, often written as cos-1x. Your scientific calculator should have a "shift" key or something similar, which you press, followed by the cosine key. That will give you the inverse cosine or arc-cosine.
