intigrate w.r.t x

Asked by sumahr | 28th Dec, 2009, 07:37: PM

Expert Answer:

Assuming you meant following function,

f(x) = ex((x-1)/x2) = ex/x - ex/x2

f(x) dx = ex dx/x -  exdx/x2

=  ex/x - ex (-1/x2) dx - exdx/x2 .................integrating by parts, only the first integral

= ex/x + exdx/x2 - exdx/x2

= ex/x + c
