Question

im just checking...coz my answer makes no sense

Find the area bounded by \(y = xe^x\) and y = 0 in the 3rd quadrant.

Answer 1

do you have this as your integral?
\[\int\limits_{-\infty}^{0}xe^xdx\]

Answer 2

yes

Answer 3

do you have the integral coming out to be
\[e^x(x-1) + c\]
then after evaluation from - infinity to 0, equalling -1?

Answer 4

i dont think there should be a +C though since it's a definite integral

Answer 5

i got 1 btw not negative...

Answer 6

:P did you evaluate in the correct order? IE F(0) - F(-inf)?

Answer 7

*facepalm* i forgot to wrote negative...i didnt see it @_@
