SUMMARY

The discussion focuses on solving for extreme values and saddle points in multivariable calculus, specifically using partial derivatives. The user expresses difficulty in handling a linear function with a raised power and seeks assistance in solving for critical points, particularly at (0,0). The approach involves separating partial derivatives and utilizing substitution to find solutions, emphasizing the importance of understanding these concepts without graphing tools.

PREREQUISITES
  • Understanding of multivariable calculus concepts, particularly partial derivatives.
  • Familiarity with critical points and their significance in determining extreme values.
  • Knowledge of substitution methods in solving equations.
  • Basic graphing skills for visualizing functions, even without a calculator.
NEXT STEPS
  • Study the method of finding critical points using partial derivatives in multivariable calculus.
  • Learn about the second derivative test for classifying critical points as maxima, minima, or saddle points.
  • Explore substitution techniques in solving nonlinear equations.
  • Review examples of extreme value problems in calculus to reinforce understanding.
USEFUL FOR

Students in multivariable calculus, particularly those struggling with extreme value problems and saddle point identification, as well as educators looking for effective teaching strategies in calculus concepts.

The Attempt at a Solution



I separated the partial derivatives. However I do not know how to solve a linear function with a raised power. I know that I will have to solve for (0,0) and another answer. Yet, I just do not know how to solve for that power. Technically I can graph the functions but I cannot use a calculator in my clac class. If anyone can help me out that would be great.

I would solve the Fx equation for y and then substitute the y value into the Fy equation, and vice versa.
 
oh I totally forgot about substitution. Thank you!
