Constants

These constants are referred to via the form Math.Constant.  For example, Euler’s constant is
Math.E

static double

E
          The double value that is closer than any other to e, the base of the natural logarithms.

static double

PI
          The double value that is closer than any other to , the ratio of the circumference of a circle to its diameter.

Methods

All methods are called by using the form Math.method(argument). The following example calls the method  and returns a value to be placed in the variable y.
double y=Math.sin(x);
