CSS Applied Mathematics QUESTION #4142
Question 1
At the point $(0, b)$ on the ellipse $\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1$, what is the radius of curvature $\rho$?
  • $\frac{a^2}{b}$✔️
  • $\frac{b^2}{a}$
  • $\frac{a}{b}$
  • $\frac{b}{a}$
Correct Answer Explanation
For ellipse $\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1$, radius of curvature at $(0,b)$ (vertex on minor axis) is $\rho = \frac{a^2}{b}$.
