Integrate using limits..

anonymous · Answer

using a riemann sum? have fun

@satellite73 , Saw the Lunar Eclipse?

anonymous · Answer

no when was it?

anonymous · Answer

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

saifoo.khan · Answer

NOW! lol.

@ERoseM use that integrating thing.

anonymous · Answer

damn it is cloudy and i am east coast

@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

anonymous · Answer

sure

saifoo.khan · Answer

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

anonymous · Answer

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

saifoo.khan · Answer

Confused? where?

anonymous · Answer

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

saifoo.khan · Answer

Why are you guys using Riemann?

anonymous · Answer

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

saifoo.khan · Answer

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

anonymous · Answer

niether have I.... !!!

anonymous · Answer

kidding....

saifoo.khan · Answer

lol, i got confused for a sec.

anonymous · Answer

Asker?  is that what u wanted? limit definition?

anonymous · Answer

Yes, thank you.
