WebbThe vector (1,0) rotated +90 deg CCW is (0,1). This calculator will tell you it's (0,-1) when you rotate by +90 deg and (0,1) when rotated by -90 deg.You must use positive angles or CW or negative angles for CCW for the correct answer (opposite of what it says to do). 2024/11/08 20:50 Webbwww.ck12.org Chapter 1.
