SUMMARY

The discussion focuses on calculating double integrals over general regions using a computer algebra system (CAS). The specific function to integrate is z = x^3 * y^4 + xy^2, bounded by the curves y = x^3 - x and y = x^2 + x for x ≥ 0. Participants emphasize the importance of determining integration limits, which are specified as X from 0 to -1 and Y from -0.25 to 0.4. The TI-89 calculator is mentioned as a potential tool for solving the integral, with a recommendation to first solve it manually for verification.

PREREQUISITES
  • Understanding of double integrals and their applications.
  • Familiarity with computer algebra systems (CAS) for symbolic computation.
  • Knowledge of integration limits and how to determine them for bounded regions.
  • Basic proficiency in using the TI-89 calculator for mathematical computations.
NEXT STEPS
  • Learn how to set up and solve double integrals in a computer algebra system like Mathematica or Maple.
  • Study the process of determining limits for double integrals over general regions.
  • Practice solving double integrals manually to gain confidence before using CAS tools.
  • Explore advanced features of the TI-89 calculator for handling complex integrals.
USEFUL FOR

Students, educators, and professionals in mathematics or engineering who are working with double integrals and seeking to utilize computer algebra systems for complex calculations.

Double integrals over General Regions. (HELP PLEASE !)

Use a computer algebra system to find the exact volume of the solid.

Under the surface z = x^3 * y^4 + xy^2

and above the region bounded by the curves y = x^3 - x and y = x^2 + x for x >= 0



How do I use a computer algebra system to find the volume.

Do you want the algorithm to find the limits for you then solve it? Or do you require the user to know the limits etc...

We need some assumptions about your program.
 


The limits for X is 0 to -1 and for Y it's -.25 to .4

Do I need a TI-89 to do this problem.
 


First, simple solve the integral by hand to get a check value against the computer system.
