This is a visual exercise on the linear transformation in dimension 2: let be a 2×2 matrix. Then M corresponds to a linear transformation of : for any point , the image of p by the linear transformation is the point .
Now the exercise gives you the matrix M , numerically described, as well as a figure representing the point p in the cartesian plane. You are simply asked to click (shoot) on where you think is the position of the image point q. At the end of a session composed of several shots, you will be given a score computed according to the average precision of your shots during the session.
Choose a level of difficulty : 1 , 2 , 3 , 4 , 5 , 6 , 7 .
