Document Summary
Total possible is 54 (50 plus 4 extra credit): find the length of the curve. , 2 x 4 x y. 4: y = ln(sec x), 0 x /4, y2 = 4x, from ( 4, 4) to (0, 0) x = (1/4)y2 , so dx/dy = y/2, and. Let y = 2 tan , so dy = 2 sec2 d . , 0 < a x b. Sixteen points: 4 each for a, b, c and e (2 for setup, 1 for calculation, 1 for answer). By symmetry, the length of the top half equals the bottom half, so double the integral and just use. Four points: 1 for symmetry, 3 for setup: find the arc length function of the curve y = 2x3/2 with starting point (1, 2). , 1 y 2, about the y-axis. t x t. )1( x: find the surface area of the solid described in part b).
