ERoseM Find the exact area (using the limit definition) between the curve f(x)=x^2+x+1, the x-axis and the vertical lines: x=-2 and x=3 one year ago one year ago

Integrate using limits..

2. satellite73

using a riemann sum? have fun

3. saifoo.khan

@satellite73 , Saw the Lunar Eclipse?

4. satellite73

no when was it?

5. ERoseM

Do I have to use the Riemann sum? that what I was questioning....

6. saifoo.khan

NOW! lol.

@ERoseM use that integrating thing.

9. satellite73

damn it is cloudy and i am east coast

10. saifoo.khan

@satellite73 ; http://knue.com/solar-eclipse-this-sunday/ Georgia people can see too. If you want to see it live i can give u the link! ;D

11. satellite73

sure

12. saifoo.khan

$\Large \int\limits_{-2}^{3} x^2 + x +1 .dx$ @ERoseM

13. ERoseM

I'm still confused, can anyone else explain it?

14. saifoo.khan

Confused? where?

15. dpaInc

you want to take the limit as n --> inf of the Riemann sum?

16. saifoo.khan

Why are you guys using Riemann?

17. dpaInc

because he said he wanted to get the area using the limit definition.... :)

18. saifoo.khan

umm.. so isn't limit thingy 3 and -2? i never studied this Riemann thingy! :D

19. dpaInc

niether have I.... !!!

20. dpaInc

kidding....

21. saifoo.khan

lol, i got confused for a sec.

22. dpaInc

Asker? is that what u wanted? limit definition?

23. ERoseM

Yes, thank you.
