Place it on a graph in quadrant IV.

The reference angle (the angle formed with the x-axis) is 60°.

The side opposite the 60° angle has value -√(3)/2.

The side adjacent the 60° angle has value 1/2.

The hypotenuse has value 1.

sin(300°) = opposite side / hypotenuse = (-√(3)/2) / 1 = -√(3)/2.

cos(300°) = adjacent side / hypotenuse = (1/2) / 1 = 1/2.

tan(300°) = opposite side / adjacent side = (-√(3)/2) / (1/2) = -√(3)/2.
