How do you calculate rotation?
Space and AstronomyWhat is the formula for rotation? Here are the rotation rules: 90° clockwise rotation: (x,y) becomes (y,-x) 90° counterclockwise rotation: (x,y) becomes (-y,x) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y) 270° clockwise rotation: (x,y) becomes (-y,x) How do you solve rotation? Video quote: So the rules for rotation algebraically. Are if it's going
