Find the exact value of the cosecant of 120 degrees. The angle is located on the unit circle and the y coordinate of this angle is the sine of 120°. The cosecant is written as 1/sin120° and this is used to find the exact value of the cosecant of 120°. The answer is given both in un-simplified form and it is also simplified by rationalizing the denominator. (A calculator would only give a numerical approximation.)
