Unformatted text preview: 2 + 3 sin t k for 0 t . Mark the start and end [10 pts] points with their coordinates. (b) Write down a parametrization of the curve. The curved part is the parabola y = x 2 . [10 pts] Please put problem 4 on answer sheet 4 4. (a) Give the symmetric equations of the line through (1 , 2 , 3) and (4 ,2 , 1). [7 pts] (b) If a ( t ) = 2 , v (1) = 2 + + k and r (1) = 0, nd r ( t ). [13 pts] Please put problem 5 on answer sheet 5 5. Find the point on the plane 2 x +3 y + z = 8 which is closest to the point (1 , 2 , 3). There is more [20 pts] than one way to do this. Any remotely relevant pictures and/or calculations will be accepted for partial credit....
