Calc 3- Triple Integral using cylindrical coordinates

Click For Summary
SUMMARY

The discussion focuses on evaluating the triple integral of the function sqrt(x^2+y^2) using cylindrical coordinates. The region of integration is defined by the circular paraboloid z=9-16(x^2+y^2) and the xy-plane. Participants emphasize the importance of determining the bounds for r as a function of z and suggest visualizing the problem by drawing a cross-section in the x-z plane to clarify the z bounds.

PREREQUISITES
  • Cylindrical coordinates in multivariable calculus
  • Understanding of triple integrals
  • Knowledge of paraboloids and their equations
  • Ability to visualize cross-sections of 3D shapes
NEXT STEPS

  • Learn how to derive bounds for integration in multivariable calculus
  • Explore visualizing 3D shapes and their cross-sections
  • Review the properties and equations of circular paraboloids
USEFUL FOR

Students and educators in calculus, mathematicians working with multivariable integrals, and anyone seeking to deepen their understanding of cylindrical coordinates and triple integrals.

Use cylindrical coordinates to evaluate the triple integral , sqrt(x^2+y^2) where the region integrated is the solid bounded by the circular paraboloid z=9-16(x^2+y^2) and the xy-plane.


I'm having trouble deciding what the bounds for r would be.

try drawing a cross section, say in the x-z plane

you should be able to find r as a function of z & the z bounds should be clear from the problem
 
Thank you!
 
no worries ;)
