The sine of an acute angle in a right triangle is the ratio of the
length of the side that is opposite the angle to the length of
the hypotenuse. The cosecant of an acute angle is the inverse
of the sine of the same angle. The inverse sine of x, or sin-¹
x, can be used to determine the measure of an acute angle
whose sine is x.
