Dear Friends
I am trying to sweep a set of points by some degree theta. So I am using this formula
newx = x;
newy = y * cos(theta) - z * sin(theta);
newz = y * sin(theta) + z * cos(theta);

Is this formula valid for any degree theta.
Because when theta=360 degree, then sin(theta) = 1.47e--05

Is this okay. Please give me some idea.
