From Google News Search: "By Region" How do you compute the volume of the solid formed by revolving the given region by using shells or disks? Q. The directions are use the best method available to find each volume. The problem: The region bounded by y=x+2, y=-x-2, and x=0 revolved about (a) y=-2 and then (b) the y-axis i am having a lot of trouble with problems like these. Please help if you can. needs to use integration thanks Asked by db2dz - Thu Feb 19 14:24:19 2009 - - 1 Answers - 0 Comments A. Well first graph the region. Always graph first so that you know what you're working with. You should see that this is a triangle. I'm going to use the disk/washer method for the first. a) y = x+2 > y = -x-2 R...r limits are -2, 0 Both are greater than the line y = -2, so each will have -2 subtract from it, bigger minus smaller V = [(x+2 + 2) - (-x-2 + 2) ] dx [-2, 0] V = - [(x+4) - (-x) ] dx [0,-2] -- just flipped the limits with the negative = - [x + 8x + 16 - x ] dx = -8 (x + 2) dx = -8 (x /2 + 2x) [0, -2) = -8 (2 - 4) = -8 (-2) = 16 b) This one is best done with the shell method because of the layout of the functions. V = 2 (-x)(x+2 - (-x-2)) dx [-2, 0] V = 2 x(2)(x+2) dx [0, -2] -- the negative in… [cont.] Answered by o - Thu Feb 19 14:55:33 2009 Find the volume of the solid generated by revolving the region bounded by the lines about the x-axis? Q. Find the volume of the solid generated by revolving the region bounded by y=1/x, x=1, x=4, and y=0 about the x-axis Asked by Gina G - Tue Jan 27 13:12:25 2009 - - 1 Answers - 0 Comments A. I want to draw your attention that there is 1 formula for calculating volume of the solid formed by rotating about the x-axis V_x = pi*[a,b] y dx and 2 formulas when rotation is about y-axis: V_y = pi*[c,d] x dy and V_y = 2 pi*[a,b] xy dx. As in your case the region is rotated around x-axis we will use the first formula V_x = pi*[a,b] y dx x=1, x=4 give us limits of integration: V_x = pi*[1;4] (1/x) dx = pi*[1;4] x^(-2) dx = = pi * -2*x^(-3) [1; 4] = pi* (-2/x^3 ) [1; 4] = = pi * (-2/4^3 + 2/1^3) = pi * (-2/64 + 2) = pi * (2 - 1/32) = = pi* 63/32 V_x = pi*63/32 Answered by Tabula Rasa - Wed Jan 28 13:46:43 2009 What is the area of the region enclosed by the parametric equation: x = t^3 - 7 t, y = 4 t^2?
Q. From graphing it on my TI-89 it appears that it never forms an enclosed region. Can anyone confirm this? Is this question a typo? Asked by kalkkid99 - Wed Apr 2 16:39:23 2008 - - 1 Answers - 0 Comments A. It does form an enclosed region, try graphing with the following limits for t: - 7 t 7, this will just show the enclosed region, or try between -5 and 5, to get a rough idea of what happens afterwards. Then just find the enclosed area, which I figure you know how to do. Answered by Smitty - Fri Apr 4 08:45:10 2008 From Yahoo Answer Search: "By Region"
