i dont get why this is improper integral...i thought improper integrals involved infinities o.O please explain why...and also pls show steps how to solve :D \[\LARGE \int_{-1}^{0} \frac{e^{\frac{1}{x}}}{x^3} dx\]

OpenStudy (lgbasallote):

ugh what did i do wrong -_-

OpenStudy (inkyvoyd):

didn't come out right :S

OpenStudy (accessdenied):

an ending bracket is missing you have +1 opening brackets

OpenStudy (accessdenied):

OpenStudy (lgbasallote):

uhmm so why is it an improper integral?

OpenStudy (lgbasallote):

and cool @AccessDenied you can read error latex haha i can only read the codes :p

OpenStudy (lgbasallote):

no one's answering :(( @cinar ?

OpenStudy (accessdenied):

my intuition is saying, this is improper because as x->0 the function tends to infinity

OpenStudy (lgbasallote):

i see...so i substitute for the limit as t approach 0?
