Sine = -0.5
Cosine = -0.866
Tangent = 0.577
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
Cotangent is ' 1/tangent' or ' Cosine / Sine'.
Yes, sine, cosine, tangent definitions are based on right triangles
Cotangent is 1 / tangent. Since tangent is sine / cosine, cotangent is cosine / sine.
First make sure your calculator is in 'Degree Mode (D)'. Then using the 'Inverse' of 'Sin' , shown as 'ArcSin' or ' Sin^(-1)' . enter '0.5', followed by '=' . The answer should be '30' ( 30 degrees).
Reciprocal of tangent is '1 /tangent' or ' Cosine / Sine '
You can use your trigonometric functions (sine, cosine, and tangent).
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.

No, it does not.
Trigonometry
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.
