## anonymous one year ago What do you suppose they're asking me to do, solve or say in this problem? pic coming ...>

do they mean the formula for f[x] and not f[t] ? and still.. Im not sure what they're asking of me here.

3. Michele_Laino

I'm sorry, I'm not good with Mathematica

4. Elsa213

I think they mean the formula for f[x]

yeah Im lost too.. maybe they just want me to say, that we used integration to create the function and the f'[x] has just reversed it?

7. Elsa213

I think so 2. :o This might help. c: https://www.mathway.com/

Maybe the question is.. why would $f[x] = \int\limits_{a}^{x} g[t] dt$ give us f'[x] ? And I am expected to explain?

9. Elsa213

Yes c:

10. ganeshie8

Yes, this question is about fundamental theorem of calculus : $\dfrac{d}{dx}\int\limits_a^xg(t)\,dt~=~g(x)$

11. anonymous

okay.. so I just need to read up on that.. thanks ganeshie8

12. Elsa213

Pfft I get no thanks. ;-;

13. Elsa213

And no medal >.<

14. anonymous

lol thanks elsa too :) but ganshie did solve the puzzle

15. Elsa213

YESH!!! >:D Thank you, Ganeshie. c:

16. anonymous

I do appreciate you coming to help though.. I really need it :)

17. ganeshie8

It seems they want you guess below relation through exercises : |dw:1437065056261:dw|

18. anonymous

Is this relationship only true because a=1 or would it be true no matter what a= ?

19. anonymous

ah, a is independent here I think

20. ganeshie8

Yeah, it doesn't matter. $$a$$ can be any number/constant.
