cosecant, cosecant function, csc

IN MATH: 1. n. in a right triangle, the ratio of the length of the hypotenuse to the length of the opposite side; the reciprocal of the sine. EX. In a 3-4-5 right triangle, what's the cosecant of the smallest angle? 2. n. the reciprocal of the sine of an angle, a trigonometric function defined for all angles except: 0°, 180°, 360°, etc. EX. Using reference angles, determine csc (225°).
