Two tanks are participating in a battle simulation. Tank A is at point (325, 810, 561) and tank B is positioned at point (765, 675, 599). (a) Find parametric equations for the line of sight between the tanks. (the solution should be x = 325 + 440t, y = 810 - 135t, z = 561 + 38t, please explain each step clearly in typefont, thank you!) (b) If we divide the line of sight into 5 equal segments, the elevations of the terrain at the four intermediate points from tank A to tank B are 549, 566, 586, 589. Can the tanks see each other?
