Use the Simpson’s Rule approximation 52 (based on two subintervals) 2 d2: — , to show that for the integral 1 :1: and estimate the error K(b — a) < _ 18011“ fabf(m)dz—Sn in this approximation, where K is the maximum of |f(4)(:r)| on the interval a S a: S b. Find the area of the plane region bounded by the line a: + y = 1 and the curve x/E + J37 = 1. 4. Find the area of the surface obtained by rotating the infinitely long curve y = e", (0 S x < 00) about the x-axis. You might need the formula /\/a2+:l;2 (lx=%x a2+x2+éln|$+Va2+xZI+C 5. a) Sketch the polar graph r = sin(29). b) Find the area of the polar region that lies inside of the circle 1' = 1/\/§ and outside r = sin(29). 6. Do only one of the problems i) and ii) below. Clearly indicate which one you select. i) Let C be the curve a: = e‘ cost y = e‘ sint where t 2 0. Show that the lentgh of C from A = (1,0) to any point P on C is equal to W times the distance from P to the nearest point Q on the circle through A centered at the origin: arc(AP) = fl m4 " ‘4‘ .0) ii) Find the centroid of the plane region that lies inside the cricle x2 + y2 = 1, outside the circle 11:2 + y2 = x, and above the z-axis. y 7. 21 Find the Maclaurin polynomial P3 .1‘ of de ree three, and the La- 15 grange remainder R3(.r), for the function f(x) 2 V1 + 3:. b) Estimate the error if the polynomial P3(z) from part a) is used to approximate 1.2. tan‘1 t t sins: — F(a:) 8.
