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.
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.
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.
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.
