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...

If sinθ=5/13 is in quadrant 2, what is the value of sin(θ+3pi/2)?

The question is cos -105. I know how to do the process for it but for some reason my answer doesn't have the right negatives. I am getting: √2 + (-√6) -------------- ...

I am doing sum and difference formulas with sin, cos, and tan. I am doing tan75 with the difference formula. So tan 120-45 I have all the things found I just don't know...
