It is the reciprocal of the sine ratio.
Neither, it is a mathematical discipline.
Tangent is the ratio between perpendicular to the base of the triangle.
Yes a tangent is a straight line thattouches a curve at only one point But there is a tangent ratio used in trigonometry
If you have a right triangle, the sine of an angle is the ratio of the opposite side to the hypotenuse.
Trig ratios or to give them their proper name are trigonometrical rations applicable to right angle triangles and they are tangent ratio, sine ratio and cosine ratio.

In trigonometry, when we look at right triangles, the cosine is the ratio of the length of the adjacent side to the length of the hypotenuse.
They don't. If they did then trigonometry would be virtually non-existent.
You plot the magnitude of the angle along the horizontal axis and the value of the trigonometric ratio on the vertical axis.
The sine of one of the acute angles in a right triangle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.
