The sin function in java.lang.Math expects a parameter expressed in radians.

I think you should use Math.sin(Math.toRadians(90))

You could use the Math.sin function where the argument is given in radians. Example:

double result = Math.sin(Math.PI / 2.0);

It has a sin(double) method among other mathematical functions. It takes the angle in radian, so you'd have to do the conversion from degree. For that purpose (and others), Math also has the PI constant.
