Osculating Circle Homework: Solving for Curvature Limit

Click For Summary
SUMMARY

The discussion centers on solving for the curvature limit of an osculating circle using the curvature equation |f''| / [1-(f')^2]^(3/2). The user attempts to evaluate the limit as it approaches -1 but encounters confusion regarding the expected result of 2. The calculations presented yield |-1| / (13)^(3/2), indicating a misunderstanding in the application of the limit process or the curvature formula.

PREREQUISITES
  • Understanding of calculus, specifically derivatives and limits.
  • Familiarity with curvature concepts in differential geometry.
  • Knowledge of the osculating circle and its properties.
  • Proficiency in applying the curvature equation |f''| / [1-(f')^2]^(3/2).
NEXT STEPS
  • Review the derivation and application of the curvature equation in differential geometry.
  • Study the properties of the osculating circle and its relationship to curvature.
  • Practice limit evaluation techniques in calculus, focusing on indeterminate forms.
  • Explore examples of curvature limits to reinforce understanding of expected outcomes.
USEFUL FOR

Students studying calculus and differential geometry, particularly those tackling problems related to curvature and osculating circles.

I know I would use the curvature equation |f''| / [1-(f')^2]^3/2 and then take the limit of that to -1. I just don't understand why I have to take the limit of the curvature and when I take the limit of the curvature I get |-1| / (13)^3/2 when the answer should be 2.
