What would be the best way to solve next three differential so that the result it is not dependant from s. I know what the x, y, and z are. I need vx, vy an vz. sqrt(vx^2+vy^2+vz^2) dvx/ds= -a b cos(theta) dx/ds sqrt(vx^2+vy^2+vz^2) dvy/ds= -a b cos(theta) dy/ds sqrt(vx^2+vy^2+vz^2) dvz/ds= -a dz/ds -a b cos(theta) dz/ds
