Plato Question!!!!Type the correct answer in each box.What is a polar form of (-1, β3 ) is ( _ , _ ) ?
Question
Answer:
Answer:(2, 120Β° )Step-by-step explanation:To convert from rectangular to polar form, that is(x, y) β (r, Ξ ), user = [tex]\sqrt{x^2+y^2}[/tex]Ξ = [tex]tan^{-1}[/tex]( [tex]\frac{y}{x}[/tex]) here (x, y ) = (- 1, [tex]\sqrt{3}[/tex])r = [tex]\sqrt{(-1)^2+(\sqrt{3} }[/tex] )^2 Β = [tex]\sqrt{1+3}[/tex] = [tex]\sqrt{4}[/tex] = 2Ξ = [tex]tan^{-1}[/tex]([tex]\sqrt{3}[/tex]) = 60Β° β related acute angleNote (- 1, [tex]\sqrt{3}[/tex]) is in the second quadrant so Ξ must be in the second quadrant.Ξ = 180Β° - 60Β° = 120Β°(- 1, [tex]\sqrt{3}[/tex]) β (2, 120Β°)
