SUMMARY

The discussion focuses on solving the Change of Variables problem using the transformation T(u,v) defined by the equations x = u^(1/3)v^(2/3) and y = u^(2/3)v^(1/3). Participants emphasize the importance of substituting these transformations into the functions to determine the new endpoints for u and v, as well as calculating the Jacobian. The need to solve for u and v to find the transformed region R is also highlighted as a crucial step in the process.

PREREQUISITES
  • Understanding of multivariable calculus, specifically change of variables.
  • Familiarity with Jacobian determinants in transformations.
  • Knowledge of function substitution techniques.
  • Ability to graphically represent regions in the Cartesian plane.
NEXT STEPS
  • Study the calculation of Jacobians for various transformations.
  • Learn about graphical representations of transformed regions in multivariable calculus.
  • Explore examples of change of variables in double integrals.
  • Practice solving for variables in transformation equations.
USEFUL FOR

Students and professionals in mathematics, particularly those studying calculus and multivariable functions, as well as educators seeking to enhance their understanding of transformations in mathematical analysis.

I'm having trouble using T(u,v) to figure out how to find the region that transforms into the the given region, R. Can anyone help?

Thank you!

Have you at least drawn the region?

yes
 
Well now substitute $\displaystyle \begin{align*} x = u^{\frac{1}{3}}v^{\frac{2}{3}}\end{align*}$ and $\displaystyle \begin{align*} y = u^{\frac{2}{3}}v^{\frac{1}{3}} \end{align*}$ into all the functions. What are the new endpoints for u and v? What's the Jacobian?

Don't I need to solve for u and v and plug in the points to figure out the region that transforms into R under T(u,v) ?
