Find the equation of the tangent plane to the surface x2 + y2 8z2 = 0 at the point (2, 2, 1) on that surface. The planes of parts (a) and (b) intersect in a line which passes through the point (2, 2, 1). Write an equation for that line of intersection, in parametric form. Find the points on the line of part (c) which are distance 1 from (2, 2, 1). If two resistors with resistances r1, r2 are connected in parallel, then the total resistance.
