How do you calculate the coordinate direction angles if the resultant force is negative?For example, the x, y, and z components of the resultant force are all negative. You use the inverse cosine of Fx/F, Fy/F, and Fz/F to find them, but aren't angles \alpha ,\beta ,\gamma all measured from the positive axes?
