trigonometry
Use the java.lang.Mathlang.Math class to compute trignometric functions. You say things like:
// calc sine of angle theta, expressed in radians
double s = Math.sin( theta );
You can leave off the Math. if you use a static import.
static import java.lang.Math.*;
...
// calc sine of angle theta, expressed in radians
double s = sin( theta );

For the most part, all the trig functions you need are in the java.lang.Math class with the same names mathematicians use namely: sin, cos, tan, asin, acos, atan, sinh, cosh, tanh.
