Solutions to Homework 9 Section 127 # 12 Let Dbe the region bounded below by the cone z= p x 2 y2 and above by the paraboloid z= 2 x y2Setup integrals in cylindrical coordinates which compute the volume of D. Circle of radius 1 traversed from left to right Solution 1 We start by making a plot showing the curve, a sample of infinitesimal displacements, and a sample of vector field outputs along the curve as shown below 1 1 x 1 y The equation of the circle is x2 y2 =. The circle of x^2 y^2 = 25 has a radius of 5 units and the center of the circle is at the point (0,0) to graph the circle you solve for y equation would be y = / sqrt(25x^2) and would look like this on the graph The equation of the radius intersecting the circle at the point (3,4) would be found as follows let x1,y1 = 0,0 let x2,y2 = 3,4.
Let F(x;y) = x2y;x 2y and let Cbe the curve r(t) = t;t2, with t running from 0 to 1 Compute the line integral I= Z C Fdr Do this rst using the notation Z C Mdx Ndy Then repeat the computation using the notation Z C Fdr answer First we draw the curve, which is the part of. The given polar equation was a circle of radius 1/2centered at (1/2,0) since r =cosθ =⇒ r2 =rcosθ Converting to rectangular coordinates we obtain x2y2 =x =⇒ (x−1/2)2y2 =1/4 However, we were unsure which values of θ were necessary to generate a complete circle It. It has the eqn of (x3)² (y2)² = 25 The center must be (3, 2) and the radius must be 5 (to get that plus inside the (xh) h must be negative for it to cancel) When this circle gets reflected, the radius won't change, but the center will If we reflect our center (3, 2) over x = 2, it would end up at (7, 2) Let's show this in our new.
If you draw a line through a circle, normally they intersect at two points The problem is asking you to show that it only intersects at one point Coincident means "occurring together in space or time", so two possible coincident points are actually one point. circle x2 y2 = 4, the cross sections perpendicular to the xaxis are right isosceles triangles with a leg on the base of the solid 13 Picture for Example 4 14 Example 5) Find the volume of the solid whose base is bounded by y = x 1 and y = x21, the cross sections perpendicular to the xaxis are rectangles of height 5. Mwe The triangle with base at x has base with length 2y where y is on the circle, so the area A of each triangle is 1/2 (2y) (2y) = 2y^2 = 2 (25x^2) The volume is just the integral of that from 5 to 5 👍 👎.
