For an acute angle in a right triangle, it is the ratio of the opposite side to the hypotenuse.
This function gives the y-coordinate of a point rotated from standard position along the unit circle. This odd function, which passes through the origin and has a period of two pi, is the reciprocal of (*) cosecant. For an acute angle in a right triangle, it is the ratio of the opposite side to the hypotenuse. For 10 points, name this trigonometric function, which gives the tangent function when divided by cosine.
