Sine= Opposite/ Hypotenuse Cosine= Adjacent/ Hypotenuse
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.
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)
Cosine(30) = sqrt(3)/2
Sine = -0.5 Cosine = -0.866 Tangent = 0.577
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.
The maximum of the sine and cosine functions is +1, and the minimum is -1.
For a right angle triangle:- hypotenuse = adjacent/cosine or hypotenuse = opposite/sine
It is cosine*cosine*cosine.
To determine the direction of a vector using the keyword "how to find vector direction," one can follow these steps: Identify the components of the vector in terms of its magnitude and direction. Use trigonometric functions such as sine and cosine to calculate the angle of the vector with respect to a reference axis. Express the direction of the vector using the angle calculated in step 2, typically in terms of degrees or radians.
use the SohCahToa method
cos(30) = sqrt(3)/2 so cosine squared is 3/4.
