Question 937178


The Unit Circle is the graph of  {{{x^2  + y^2 = 1}}}.  For an angle in standard position, the point of intersection of the terminal side of the angle with the Unit Circle gives the {{{cosine}}} and {{{sine}}} of the angle.  The x-coordinate is the{{{ cosine}}}, and the y-coordinate is the {{{sine}}}.  

for {{{-300}}}° angle the{{{ cosine=1/2}}} and {{{sine=-sqrt(3)/2}}}   

so,the coordinates of the point of intersection of the terminal side of {{{-300}}}° angle are ({{{1/2}}}, {{{-sqrt(3)/2}}})
