100*.005= .5= 1/2 so sin(100(pi)(.005))= sin(pi/2)= 1.

If your calculator is not giving you 1, you do not have it in [b]radian[/b] mode. That is the problem with depending upon a calculator rather than KNOWING what you are doing. You should know, without having to use a calculator, that sin(pi/2)= 1.
