SUMMARY

The discussion focuses on solving two calculus problems involving implicit differentiation. The first problem requires finding the equation of the tangent line to the curve defined by the equation xy + y = 2 at the point (1,1). The second problem involves evaluating dy/dt for the function xy² = 4, given dx/dt = -5, x = 4, and y = 1. The key technique emphasized is implicit differentiation, which is essential for both problems.

PREREQUISITES
  • Understanding of implicit differentiation
  • Knowledge of calculus concepts such as tangent lines
  • Familiarity with derivatives and their applications
  • Basic algebra skills for manipulating equations
NEXT STEPS
  • Practice implicit differentiation with various functions
  • Learn how to find tangent lines for different curves
  • Explore the chain rule in relation to parametric equations
  • Study related rates problems in calculus
USEFUL FOR

Students studying calculus, particularly those needing assistance with implicit differentiation and tangent line problems, as well as educators looking for examples to illustrate these concepts.

Need answers for 2 questions please:

1.) Find the equation of the line tangent to the curve at the point.

xy + y = 2 ; (1,1)

2.) Evaluate dy/dt for the function at the point

xy^2 = 4 dx/dt = -5 x = 4, y = 1

Thank You

You need to show us an attempt at a solution before we can help you. But I'll tell you that you need implicit differentiation for this.
