Thanks for the addition to the arclength page on wikibooks calculus. I had not thought of putting that in. Juliusross 11:14, 13 October 2005 (UTC)

Sorry to be fussy, but you should say that you are assuming that f and g have continuous first derivatives.

Also the last line "This is equivalent to:" the integral is correct. But it is not quite the definition of the Riemann integral as it is usually given (as you have c_i and d_i instead of just c_i). It works because \sqrt{a^2+b2} is continuous function of two variables. I am not sure if it is worth mentioning it as it is a technicality.

If you want me to I can think if I can find a way around this problem Juliusross 18:14, 22 October 2005 (UTC)
