5) 6) Prove: u-v=vu for vectors u,v in V₁. Show all steps clearly, do not skip steps! Use vector components, and provide specific reasons for each step. Start from one side and get to the other, that is, work only on one side (do not "meet in the middle"). Given x²-4y²-16z² =4 (a) Rewrite into standard form and name/identify the type of surface. (b) Find the equations of the traces of the surface in the following planes (write "None" if no trace). Sketch and name the type of trace obtained. (i) xz-plane (ii) xy-plane (iii) trace in the planes x = ±4 (c) Sketch an accurate representation of the surface including traces and intercepts (z-axis pointing up).
