Unformatted text preview: P = (1 , ,1). (b)[3 pts] Find the point at which this plane intersects the line x = 3 t , y = 1 + 2 t , z =1 + t . 3. (10 pts) Let C be the curve parametrized by the vector r ( t ) = ln t i + t 2 2 j + t √ 2 k , 1 ≤ t ≤ 2 . Find the arc length function s ( t ) for 1 ≤ t ≤ 2. 4. Consider the planes λx + 2 y + 3 z = 1 , x + y + z = 1 . (a)[4 pts] Find λ so that these planes are perpendicular. (b)[6 pts] For the value of λ found in part (a), ±nd an equation for the intersection l of the given planes....
