Hi

6 trig functions of 5pi/6. (150°)

using the (cosx,sinx) summary below:

sin 150° = 1/2

csc 150° = 1%2F%281%2F2%29+=+2

cos 150° = -sqrt%283%29%2F2

sec 150° = +1%2F%28-sqrt%283%29%2F2%29+=++-2%2Fsqrt%283%29=+%28-2%2F3%29sqrt%283%29

tan 150° = %281%2F2%29%2F%28-sqrt%283%29%2F2%29+=+-1%2Fsqrt%283%29=+-sqrt%283%29%2F3
