How do you differentiate (x-y) using implicit differentiation?

Click For Summary
SUMMARY

The discussion focuses on the process of differentiating the expression (x - y) using implicit differentiation. The correct derivative is established as dy/dx, with the clarification that differentiation must be performed with respect to a specific variable. Participants emphasize the importance of stating the variable of differentiation to avoid confusion, particularly when considering expressions like dx/dy.

PREREQUISITES
  • Understanding of implicit differentiation
  • Familiarity with derivatives and notation (dy/dx)
  • Knowledge of basic calculus concepts
  • Ability to identify dependent and independent variables
NEXT STEPS
  • Study the rules of implicit differentiation in calculus
  • Practice differentiating various implicit functions
  • Explore examples involving multiple variables in implicit differentiation
  • Learn about the applications of implicit differentiation in real-world problems
USEFUL FOR

Students studying calculus, mathematics educators, and anyone looking to strengthen their understanding of implicit differentiation techniques.

I looked through my notes and couldn't figure out how to differentiate

(x - y)

using implicit differentiation. Could someone help with that and I should be able to work out the rest of my question :)

Just a thought now, would it be

1 - dy/dx

?
 
i think you are correct
its

1-y'
 
Why couldn't it be dx/dy-1? You need to state what you are differentiating wtih respect to.
