Welcome to James Sun's Homepage

Here is an applet I created to help students practice their unit circle.
I think it's pretty self-explanatory.
Update: whenever you click 'New Problem', a timer starts, and the applet displays the time it took you to solve the problem when you click 'Show Answer'.

(this page doesn't really work yet, and probably won't for a while, I think 000webhost doesn't support ASP.NET)

Applet Instructions:
Make sure you click in the applet area first. Arrow keys control "David". WASD keys control "James". And yes, you will realize that James moves faster than David. (David is my little bro/pet).
This was my first applet; it doesn't really have much use; I just wanted to test a simple program on the web.
