One of the most common played sports in the U.S is basketball and majority of people has played the game. There are those just so good that they can shoot the ball in the air and it goes in no matter. Take fictional character Shintaro Midorima from Kuroko no Basket for example. There are a number of things that we can go into on how and why they are able to make their shots but there is one thing most people will not considered unless your apart of the profession which is quadratic functions. I know like how does any form of math involves basketball except for keeping score but let me explain. In the gif below you see Shintaro shoot a full court shot and that man has yet to miss any. The reason for this is because he shoot at a high angle and lines up the balls trajectory with the net. In a more mathematical sense he is shooting the ball and it takes the form of a concave down parabola which guarantees the shot success. Also his domain is from any spot on the court meaning he can guarantee shot from anywhere on the court.
