Calculate the distance between these two points:

(3;π/2;−1) and (5;3π/2;5) (cylindrical coordinates)

(10;π/4;3π/4) and (5;π/6;7π/4) (spherical coordinates)

Do I need to put them in cartesian coordinates and continue the calc. or can I do with integrals?

2. Relevant equations

->dl = dr ûr + r d∅ û∅ + dz ^k

->dl = dr ûr + r dθ ûθ + r sin (∅) û∅

3. The attempt at a solution
