This depends on whether 23 is in radians or degrees. If it is in degrees, then the answer is approximately 0.92. If it is in radians, then the answer is approximately -0.53.
cos(23 deg) = 0.9205
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 is 1
-1<cosine<1
Cosine is 0.5
The Y-Intercept of the cosine function is X = 0, Y = cosine(0) = 1.
It is cosine*cosine*cosine.

Cosine 0 is 1
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.
The inverse of the cosine is the secant.
Reciprocal of Cosine is Secant
