Find \(\large\sf sin\theta~ if ~cot\theta~ =~ -2 ~and ~cos\theta~ <~ 0.\)
\[\cot(x) = \frac{ \cos(x) }{ \sin(x) }\]
\[-2*\sin(x) = \cos(x)\]
sin(x) = -(1/2) cos(x)
draw a triangle in the correct quadrant.|dw:1418577682291:dw| It helps to remember that cos can be thought of as the "x value" and sin as the "y value"

notice that the easiest way to get x/y = -2 is make x -2, and then y=1 with those numbers, figure out they hypotenuse. you get sqr(1^2 + (-2)^2) = sqr(5) now you can write down the sin or cos. sin = y/hyp
