Hi. 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

Just multiply both sides by ds. Then they aren't depending on s.
