1. cot theta = -root3

and theta is between 90 - 180

find sin theta and cos theta

i know cot theta can be set as 1/tan theta or cos theta / sin theta, but i have no idea how to get a single sin or cos

Thanks
2. Cot theta = Costheta/Sintheta

=> Costheta/Sintheta=-rt3

Damnit. I cba to use latex. >.>
3. Take an equilateral triangle with sides of length two and split it in half. Work out the length of the remaining sides and that will give you the sine and cosine you require.
