### Re: Arc Length

Hi;

Δyi/Δxi approaches the derivative of the function f’(x):

Would it be better to say the derivative of f(x)?

Nice example using the catenary.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Hi MathsIsFun,

Neat diagrams and illustrations. Thanks.
