a. What angle of rotation maps P onto P’? b. What are the x- and y-coordinates of P’ to the nearest thousandth? c. What translation rule maps P onto P’?
You can model a star’s “rotation” in the coordinate plane. Place the North Star at the origin. Let P(1, 0) be the position of the star at the moment the camera’s shutter opens. Suppose the shutter...
