Chapter 13: Problem 4

Find the intercepts and sketch the graph of the plane. $$ x+y+z=3 $$

Short Answer

Expert verified
The intercepts are \(x = 3, y = 3, z = 3\). These intercepts define a plane in the 3D Cartesian coordinate system.

Step by step solution

01

Find the x-intercept

To find the x-intercept, set y and z as zero in the equation \(x+y+z=3\). This simplifies to \(x+0+0=3\), or \(x=3\). So the x-intercept is \(x=3\).
02

Find the y-intercept

To find the y-intercept, set x and z as zero in equation \(x+y+z=3\). This simplifies to \(0+y+0=3\), or \(y=3\). So the y-intercept is \(y=3\).
03

Find z-intercept

To find the z-intercept, set x and y as zero in equation \(x+y+z=3\). This simplifies to \(0+0+z=3\), or \(z=3\). So the z-intercept is \(z=3\).
04

Plot the intercepts

Now, plot these three intercepts on the Cartesian coordinate system. The intercepts are points (3,0,0), (0,3,0), and (0,0,3). Connect these points and fill in the plane bounded by these points to sketch the graph of the plane.

Sketch the region \(R\) whose area is given by the double integral. Then change the order of integration and show that both orders yield the same area. $$ \int_{0}^{2} \int_{x / 2}^{1} d y d x $$

Use a double integral to find the area of the region bounded by the graphs of the equations. $$ y=x^{3 / 2}, y=x $$

Evaluate the partial integral. $$ \int_{0}^{\sqrt{4-x^{2}}} x^{2} y d y $$

Use the regression capabilities of a graphing utility or a spreadsheet to find the least squares regression quadratic for the given points. Then plot the points and graph the least squares regression quadratic. $$ (-4,5),(-2,6),(2,6),(4,2) $$

Set up the integral for both orders of integration and use the more convenient order to evaluate the integral over the region \(R\). $$ \begin{aligned} &\int_{R} \int \frac{y}{1+x^{2}} d A\\\ &R: \text { region bounded by } y=0, y=\sqrt{x}, x=4 \end{aligned} $$
