SUMMARY

The discussion focuses on the total differential and its integration, specifically the equation dz=(∂z/∂x)dx+(∂z/∂y)dy. The user expresses confusion regarding the integration process, leading to a contradiction when attempting to derive z(x,y). The integration steps presented are ∫dz=∫(∂z/∂x)dx+∫(∂z/∂y)dy, which incorrectly suggests that z(x,y) equals z(x) plus z(y) plus a constant. This indicates a misunderstanding of the relationship between partial derivatives and total differentials.

PREREQUISITES
  • Understanding of partial derivatives
  • Familiarity with total differentials
  • Basic knowledge of integration techniques
  • Concept of multivariable functions
NEXT STEPS
  • Study the properties of total differentials in multivariable calculus
  • Learn about the correct application of integration in the context of partial derivatives
  • Explore examples of total differentials with specific functions
  • Review the Fundamental Theorem of Calculus as it applies to multiple variables
USEFUL FOR

Students studying calculus, particularly those focusing on multivariable functions and total differentials, as well as educators seeking to clarify integration techniques in this context.

Homework Statement



I'm kind of confused with the total differential, because when i integrate it i get a contradiction, so i wonder if anyone could tell me what I'm doing wrong, please see the attachment to see my problem.

dz=(∂z/∂x)dx+(∂z/∂y)dy

∫dz=∫(∂z/∂x)dx+∫(∂z/∂y)dy

which would give z(x,y)= z(x)+z(y) + constant
