A particle is located at x = 2 , y = 3 , z = 6 in Cartesian (rectangular) coordinates. a. What are the cylindrical coordinates of the particle ( r, θ, z ) ? b. What are the spherical coordinates of the particle ( r, θ, φ ) ? 3. A vector v = v x δ x + v y δ y + v z δ z has Cartesian components v x = 1 , v y = 2 , and v z = 3 . a. What are the components of v in cylindrical coordinates ( v r , v θ , v z )? b. What are the components of v in spherical coordinates ( v r , v θ , v φ )? 4.
