X2+y2+z216 Graph

Because there are 2 ellipsoid graphs to choose from, we look at the major axis in the function and pick the graph with the corresponding major axis x axis radius = 1, y axis radius = (sqrt(1/4))^2 z axis radius = (sqrt(1/9))^2 We see the major axis is the x axis, and the corresponding graph is VII This is graph VII.

Graph x^2y^2=16 x2 y2 = 16 x 2 y 2 = 16 This is the form of a circle Use this form to determine the center and radius of the circle (x−h)2 (y−k)2 = r2 ( x h) 2 ( y k) 2 = r 2 Match the values in this circle to those of the standard form The variable r r represents the radius of the circle, h h represents the xoffset from the origin, and k k represents the yoffset from origin. In Figure 1118 (a), we show part of the graph of the equation x 2 y 2 = 1 by sketching 3 circles the bottom one has a constant zvalue of 15, the middle one has a zvalue of 0 and the top circle has a zvalue of 1 By plotting all possible zvalues, we get the surface shown in Figure 1118 (b) This surface looks like a “tube,” or a.

 Since the surface is in the form x = f ( y, z) x = f ( y, z) we can quickly write down a set of parametric equations as follows, x = 5 y 2 2 z 2 − 10 y = y z = z x = 5 y 2 2 z 2 − 10 y = y z = z The last two equations are just there to acknowledge that we can choose y y and z z to be anything we want them to be. EXAMPLE 1415 Suppose the temperature at (x,y,z) is T(x,y,z) = e−(x2y2z2) This function has a maximum value of 1 at the origin, and tends to 0 in all directions If k is positive and at most 1, the set of points for which T(x,y,z) = k is those points satisfying x 2y2 z = −lnk, a sphere centered at the origin The level surfaces are the. 2 (i) The lower half of the ellipsoid 2x2 4y2 z2 = 1 Since z isafunctionofxandy, we have z = p 1−2x2 − 4y2, so a parameterization ~r(x,y) = x~i y~j p 1− 2x2 −4y2~k where 2x2 4y2 6 1 (ii) The part of the sphere x2 y2 z2 = 16 which lies between the planes z = 2 and z = −2.

For example, if we want to plot the top half of the sphere with equation x^2 y^2 z^2 = 16, we solve for z and obtain z = sqrt (16 x^2 y^2) or z = sqrt (16 r^2) Now we draw the graph parametrically, as follows > cylinderplot ( r,theta,sqrt (16r^2),r=04,theta=02*Pi);.

Which points from the point (x,y,z) toward the origin and has length p x2 y2 z2 (x2 y2 z2)3/2 = 1 (p x2 y2 z2)2, which is the reciprocal of the square of the distance from (x,y,z) to the origin—in other words, F is an “inverse square law” The vector F is a gradient F = ∇ 1 p x2 y2z2, (1611) which turns out to be extremely. Y 2 z 2 = 16, how is the graph affected?.

Answer (1 of 3) Well, let's think of it On y=0, we have 1/z² = x² Which is z²=1/x² Solving for z would give you two real equations, z=1/x and z=1/x So on the XZ plane it has a curve that is described by 1/x and 1/x Similarly on the yz plane when you set x to be zero But on the xy plane f. Where the two surfaces intersect z = x2 y2 = 8 − x2 − y2 So, 2x2 2y2 = 8 or x2 y2 = 4 = z, this is the curve at the intersection of the two surfaces Therefore, the boundary of projected region R in the x − y plane is given by the circle 16 3 x(2 −x2)1/ 2 32 3 arcsin x. 1 $\begingroup$ This figure is the (double) cone of equation $x^2=y^2z^2$ The gray plane is the plane $(x,y)$ You can see that it is a cone noting that for any $y=a$ the projection of the surface on the plane $(x,z)$ is a circumference of radius $a$ with equation $z^2x^2=a^2$.

The Standard Form of an Ellipse Centered at The Origin Recall that the equation of a circle centered at the origin has equation x 2 y 2 = r 2 where r is the radius Dividing by r 2 we have x 2 y 2 = 1 r 2 r 2 for an ellipse there are two radii, so that we can. F(x,y,z) = x2 y2 y2 and the constraint is g(x,y,z) = x y z = 6 The vector equation ∇f = λ∇g gives the system 2x = λ, 2y = λ, 2z = λ Therefore, x = y = z, and as the sum is 6, then (x,y,z) = (2,2,2) and the product is 8 16.
