@Photon336

OpenStudy (photon336):

let's try to graph the two functions first

OpenStudy (marcelie):

okay

OpenStudy (mww):

yes always sketch if asked, on same axes,

OpenStudy (marcelie):

oh okay so then when it says x=1 , x=1 is that asking for the points ?

OpenStudy (mww):

No those are telling you the boundaries

OpenStudy (photon336):

I'm pretty sure it's asking for the area between the curves where x = 1 x = -1 are the bounds of integration.

OpenStudy (marcelie):

ah okay so then

OpenStudy (photon336):

let me post another image

OpenStudy (marcelie):

okie

OpenStudy (photon336):

\[ http://prntscr.com/bfp6zv \]

OpenStudy (photon336):

my guess is that we integrate on the x axis

OpenStudy (photon336):

\[\int\limits_{-1}^{1} (e^{x}-(1+x^{2}))~dx\]

OpenStudy (photon336):

@zzr0ck3r @Zale101

OpenStudy (marcelie):

okay so then its that the f(b)- f(a) ?

OpenStudy (mww):

You always do the upper curve minus lower curve. e^x rises faster than x^2 + 1 over the interval (and you can verify by sketch) |dw:1465792004638:dw|
