SUMMARY

The discussion focuses on calculating the volume of the region enclosed by the parabolas defined by the equations z = 1 - y² and z = y² - 1, with x ranging from 0 to 2. The y bounds are established as -1 to 1, where the parabolas intersect. The solution involves setting up a double integral with constant limits for x and y, specifically integrating the function (y² - 1) - (1 - y²) over the specified bounds. The final solution is achieved by expressing the x-coordinate as f(y,z) = 2 and integrating with respect to y and z.

Homework Statement



Find the volume of the region enclosed by z = 1 - y^2 and z = y^2 - 1 for x lying between 0 and 2 inclusive.

Homework Equations






The Attempt at a Solution



I know that the y bounds are from -1 to 1, where the parabolas meet. x bounds are from 0 to 2. So would the integral simply by the double integral , x from 0 to 2, y from -1 to 1 of the (y^2 -1) - (1 - y^2)? I'm confused at this point. All the limits of integration are constant..

Ah no worries, found out how to solve it! I expressed the x coordinate as f(y,z)=2. Then integrated this function with respect to y and z, with the bounds I specified. Thanks!
