Well, for sine, tangent and cosine ratios, you can easily solve these using the methods in the java.lang.Math class.

http://java.sun.com/javase/6/docs/api/java/lang/Math.html#sin(double)
http://java.sun.com/javase/6/docs/api/java/lang/Math.html#tan(double)
http://java.sun.com/javase/6/docs/api/java/lang/Math.html#cos(double)

If you need further help, you should post with a more specific problem (not just 'I got stuck with it').

 

I had to do a project like this is high school, and the hardest part for us was making an accurate graph

if you are doing a graph, make sure you set up constants for distances between points, because once you get to really really high numbers, you will end up with an inaccurate graph due to the large gap between 2 possible answers. Make sure that if 2 points on your graph are too far apart, it tests some possibilities between the 2 points so that you get a more accurate depiction of how the line should curve
