Pardon? To which aspect of the car are you referring? There are ratios between the gears, but they are not trigonometrical. (Unless you are analysing the advanced trig. of the teeth geometry of the gears themselves... but then you would not be asking questions like that since you'd have a Degree in Engineering!).
the adjacent side over the hypotenuse
The "sin" button on a calculator gives the sine trigonometric ratio of the given angle.
There is no particular name for the trigonometric ratio which depends on the measure of a specific angle.
subtract 90 from it and find the trig ratio of that and it will be equal to the trig ratio that is over 90 degrees
Trigonometric ratios, by themselves, can only be used for right angled triangles. The law of cosines or the sine law can be used for any triangle.

A cosine is a trigonometric ratio and is not capable of liking or disliking anything!
tangent
cos(22) is a trigonometric ratio and, if the angle is measured in degrees, its value is 0.9272

You plot the magnitude of the angle along the horizontal axis and the value of the trigonometric ratio on the vertical axis.
