Question

integral of e to the power of -x^2..help to solve this plz...

Answer 1

do you know about beta and gamma functions ?

Answer 2

good try, but that is not correct.
you cannot pull out variables out of integration, only constants.
\(\huge \int\limits_{}^{}(\frac{ 1 }{ -2x })\frac{ -2x }{ 1 }e ^{-x ^{2}}\ne \frac{ 1 }{ -2x } \int\limits_{}^{}\frac{ -2x }{ 1 }e ^{-x ^{2}}\)

Answer 3

thank you..but already solve it...by using taylor expansion..

Answer 4

sry dont know what was i thinking....
Again Sorry for misleading you and thanks @hartnn
