## anonymous 3 years ago Anybody here knows what is distance formula for curved geometry?

1. anonymous

in non-euclidean geometry

2. anonymous

why are you learning non-euclidean... o.O

3. anonymous

are you refering to line integrals?

4. anonymous

I am trying to find speed of light using non-euclidean geometry........

5. anonymous

@completeidiot Actually I need formula to find distance between two points in curved space....... is that same as line integral?

6. anonymous

there is a formula, but i dont know it off the top of my head

7. anonymous

can you give me any clue or the name of formula? I will look online too

8. anonymous

$\int\limits_{a}^{b}\sqrt{1+[f'(x)]^2}dx$

9. anonymous

that's line integral isn't that? I took calc II

10. anonymous

too many note books to look through

the speed of light is constant. if that meant something to you :)
