They both are trig functions, obviously. And they both represent a ratio that is the opposite side of a right triangle from the angle of interest, divided by one of the other sides.
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
Sine = -0.5 Cosine = -0.866 Tangent = 0.577
Reciprocal of tangent is '1 /tangent' or ' Cosine / Sine '
You can choose either or but tangent which is sin/cos seems to be the most common way.
Yes, sine, cosine, tangent definitions are based on right triangles
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
Cotangent is ' 1/tangent' or ' Cosine / Sine'.

No, it does not.
The cosine is ±1/sqrt(5) = ±0.4472 (approx).
The ratio of sine and cosine.
