adjacent/hypotenuse
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)
The sine, cosine and tangent are used to find the degrees of a right angle triangle.
You measure it. Depending on the information provided, you can also calculate it, for example using trigonometry. ======================== Work done= Force vector . Displacement vector=Force*displacement*cos a, where a is the angle between the force and the displacement. So you have the values of work force and displacement then you can do the cosine inverse of the ratio of work done to the product of the force and displacement. That will give you the angle.
the angle of incidence is equal to the angle of reflection
Law of Reflection
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
