Partial differentiation question

Click For Summary
SUMMARY

The discussion centers on solving a partial differentiation problem for a university assignment. The user successfully identified stationary points at x = -2, x = 2, y = -1, and y = 1 by applying the quotient rule to find partial derivatives. However, they express uncertainty regarding the correctness of their solution and seek clarification on the significance of a vertical line segment in the numerator of the function. Additionally, they express frustration about finding the second-order derivative using the quotient rule.

PREREQUISITES
  • Understanding of partial differentiation
  • Familiarity with the quotient rule in calculus
  • Knowledge of stationary points and their significance
  • Basic concepts of second-order derivatives
NEXT STEPS
  • Review the application of the quotient rule in partial differentiation
  • Study methods for finding second-order derivatives
  • Explore the significance of stationary points in multivariable calculus
  • Learn about common pitfalls in interpreting mathematical notation
USEFUL FOR

Students studying calculus, particularly those focusing on multivariable functions and partial differentiation, as well as educators looking for examples of common student challenges in these topics.

Hi guys,

I have the following question for a uni assignment, I have done part A and found the stationary points to be at

x=-2 x = 2
y=-1 y=1

Not sure if it is correct though.

I did this by using finding the partial derivatives using the quoitent rule, then making the partial derivatives equal to zero and solving for x and y. Now the second part of the question asks to find the second order DE, which would be an absolute pain to do using the quoitent rule. I am really, really lost guys. :cry:

Whatever does the vertical line segment in the numerator signify??

i think its a full stop that shouldn't be there
