Re: Curvature
| Peter Scales | 09 Jul 2009 12:22 |
Hi Bill,
I don't think so.
Curvature must have a dimension of L^-1
Also please note a typo in my result for d2y/dx2
It should have been:
d2y/dx2 = -b^2.(b^2.x^2+a^2.y^2) / a^4.y^3
Regards, Peter Scales.

Hi Peter,
For the curvature I have (a^4*b^4)/[(a^4*y^2 + b^4*x^2)^(3/2)]
Regards
Bill

Find and prove the numerical value of the curvature at the point (x,y) of the ellipse (x^2/a^2) + (y^2/b^2) = 1.
What is the ratio of the greatest to the least curvature of the ellipse ?.
