cos(55) = 0.022126756261956
The value of the cosine of 55 degrees is approximately 0.5736. This value can be found using a scientific calculator or trigonometric tables. Cosine values are used in various applications, including physics and engineering, to analyze angles and distances.
0.5735764264 (nearest 10 decimal places).
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
cos(30)cos(55)+sin(30)sin(55)=cos(30-55) = cos(-25)=cos(25) Note: cos(a)=cos(-a) for any angle 'a'. cos(a)cos(b)+sin(a)sin(b)=cos(a-b) for any 'a' and 'b'.
0.5735764264 (nearest 10 decimal places).
cos(35)sin(55)+sin(35)cos(55) If we rewrite this switching the first and second terms we get: sin(35)cos(55)+cos(35)sin(55) which is a more common form of the sin sum and difference formulas. Thus this is equal to sin(90) and sin(90)=1
It is cosine*cosine*cosine.
Inverse of Cosine is 'ArcCos' or Cos^(-1) The reciprocal of Cosine is !/ Cosine = Secant.
If you have a suitable calculator, you can find it directly. It is also the same as the sine of 55 degrees, which can be looked up in many tables.
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.
Cosine is 0.995
Reciprocal of Cosine is Secant
Cosine of -90 is 0.
Cosine is 0.766
