Ответ:
note : the polar coordinates is : (r , θ)
Another representation is (x, y) : x=r cos(θ) and y = sin(θ) and : r =√(x²+y²)
in this exercice : r = 1 and θ = 5π/6
so : x= 1.cos(5π/6) and y = 1. sin(5π/6)
but : cos(5π/6) = cos (π - π/6) = - cos(π/6 ) = (- √3)/2
sin(5π/6) = sin (π - π/6) = sin(π/6 ) =1/2
Another representation is : ( (- √3)/2 , 1/2)
