Hi everyone ... I am a first time poster from South Africa. I have been visiting the forum for some time. I am busy teaching myself calculus and physics.(adsbygoogle = window.adsbygoogle || []).push({});

I have hiccup with the concept of definite integral and arc length of a function. In my understanding these should be the same thing.

But looking at the formulas for calculating each, they appear to be different things. What am I missing?

Are they the same thing or different things?

Thanks,

Sithe
