adjacent/hypotenuse
The intensity of a wave varies with the square of the cosine of the angle of incidence. This relationship is known as the cosine squared law. As the angle of incidence increases, the intensity of the wave decreases due to the spreading of energy over a larger area. It is an important concept in understanding how light behaves when interacting with surfaces.
Many (most) books of tables listing logs also list cosines. First look up the cosine, and then look up that number in the log lists. The answer is the log-cosine - I hope that's what you mean.
The Lambert Cosine Law states that the intensity of light reflected off a surface is directly proportional to the cosine of the angle between the incoming light and the surface normal. This law helps to explain how the brightness of a surface changes based on the angle of incidence of light.
It has only magnitude and no direction. It depends on magnitude of two vectors which are multiplying and cosine of angle between them. A . B = AB (cosine of angle between them). Best example is 'work done by a force' = force . displacement = Fd(cosine of angle between force and displacement)
In physics, cosine function is used to determine the x-component of a vector. So cos(22) in physics would give you the x-component of a vector that makes an angle of 22 degrees with the positive x-axis.
Sine of the angle to its cosine.
Sine and the cosine of the angle.
In a right angle triangle it is: cosine ratio = adjacent/hypotenuse
Fora right angle triangle: cosine angle = adjacent/hypotenuse
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.
It is the ratio of the length of the adjacent side to that of 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.
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.
