Trig Help

This is a nice little app that uses a unit circle to a how the triangle the sin, cos, and tan values are based on.  You input the degree measurement ant it gives you the decimal values for sin, cos, and tan.  Further more, it shows the input value in bothe degrees and rads.

There is also the sector that allows you to find the inverse values and the values are given in a value plus 360 degrees.  Then there is a solver page that I am still figuring out how to use and a reference page of formulas.  This makes a nice reference app for trig students.  The only real gripe I have with this app is the apparent lack of instructions on using the app.  I do not know if I missed them or there are none.
