Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
Yes, sine, cosine, tangent definitions are based on right triangles
No, it does not.

It depends on what information you already have. For example, if you know the length of two sides of a triangle, you can easily find the tangent. Or, if you know the length of two angles and a side, you can find the other sides as well, using the tangent, cosine, and sine as needed.

Sine = -0.5 Cosine = -0.866 Tangent = 0.577
If you know the angle's sine, cosine, or tangent, enter it into the calculator and press <inverse> sine, cosine, or tangent. On MS Calc, in Scientific Mode, using Degrees, enter 0.5, then check Inv and the press sin. You should get 30 degrees. The other functions work similarly.

Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.

They are used to find the angle or side measurement of a right triangle. For example, if 2 sides of a right triangle have known values and an angle has a known measurement, you can find the third side by using sine, cosine or tangent.
Sine of the angle to its cosine.
It is a FALSE statement.
