I am studying Calculus. But 2 problem make me stuck, Does ant Tutor help me with this so that I could understand better.

hope from your helping..

1. a) Find the arc length of the function 3(t) for the curve given by the graph of t) 2 (6' sin 75, 6'5 cos t, st) measured from the point (0, 1, ) in the direction increasing t. b) Reparametrize the curve in part (a) with respect to arc length. c) Find the point P four units in the direction of increasing 15, along the curve described in parts (a) and (b). 2. Recall from class that for a terrariable function z 2 f (33,11), a level curve 1s a trace parallel to the gayplane at z 2 k, where k is some constant. A representative collection of level curves provides a contour map of the surface. a) Sketch the contour map of 9(93, y) 2 6 3m 23; for k 2 6, 0,6,12. b) Sketch the contour map Mas, y) 2 x2 y2 for k 2 0, 1,4, 9. (Hint: h describes a quadric surface)
