It is the ratio of the length of the adjacent side to that of the hypotenuse.
Sine and the cosine of the angle.
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side of that angle to the hypotenuse.
The cosine function is mathematical equation to determine the adjacent angle of a triangle. The cosine of an angle is the ratio of the length of the hypotenuse: so called because it is the sine of the co-angle.
The three basic ratios are sine, cosine and tangent.In a right angled triangle,the sine of an angle is the ratio of the lengths of the side opposite the angle and the hypotenuse;the cosine of an angle is the ratio of the lengths of the side adjacent to the angle and the hypotenuse;the tangent of an angle is the ratio of the lengths of the side opposite the angle and the the side adjacent to the angle.
Sides have lenght, angles do not. Cosine is the ratio of the adjacent side to the hypotenuse. Cosine can be used to find either of these sides if the other is known.
In a right angle triangle it is: cosine ratio = adjacent/hypotenuse
Fora right angle triangle: cosine angle = adjacent/hypotenuse
Sine of the angle to its cosine.
Sine and the cosine of the angle.
In a specific angle for a right triangle the cosine ratio is the ratio between the lengths of the adjacent side (side touching the angle) and the hypotenuse (longest side).
In a right triangle, the cosine of an angle is defined as the ratio of the adjacent side of that angle to the hypotenuse.
The cosine function is mathematical equation to determine the adjacent angle of a triangle. The cosine of an angle is the ratio of the length of the hypotenuse: so called because it is the sine of the co-angle.
The Sine ratio is Sine(angle) = opposite side / hypotenuse side. This is written in 'short-hand' as Sin(angle) = o / h Similarly the cosine ratio is Cosine(angle) = adjacent side / hypotenuse side. Cos(angle) = a/h Similarly the tangent ratio is Tangent(angle) = opposite side /adjacent side. Tan(angle) = o/a NB THe sides refer to the sides of a right-angled triangle. NNB The angle referred to is NOT the right angle, but a selected angle from the other two angles.

Power factor is the ratio of the angle between the voltage and current.In the power triangle cosine angle is the ratio between them...
If you mean cosine then it is angle ratio found in a right angle triangle which is adjacent/hypotenuse
Sides have lenght, angles do not. Cosine is the ratio of the adjacent side to the hypotenuse. Cosine can be used to find either of these sides if the other is known.
