A polar coordinate (r;θ) is given, then (x;y)=(r×cosθ;r×sinθ)

A) (22cos(135),22sin(135))=(22×22;22×22)=(2;2)

B) (22cos225,22sin225)=(22×22;22×22)=(2;2)

C) (22cos(315),22sin(315))=(22×22;22×22)=(2;2)

D) (22cos45,22sin45)=(22×22;22×22)=(2;2)

E) (22cos135,22sin135)=(22×22;22×22)=(2;2)

Choice (E) does not represent (2;2).
