TRIG 1/2 ANGLE FORUMLAS
The questions are: "If sin B = -1/3 with B in QIII, find tan B/2. Also find sin B/2
The answer for tan B/2 is-3-2sqrt(2)
The answer for sin B/2 is \sqrt((3+2\sqrt(2))/(6))
These are answers from the back of the book. I can't figure out how to work these problems out. Please help.
