Improper integral with variable

  1. Apr 23, 2009 #1
    With the help of F:[0-> infinity) F(t)= S( (e^(-tx)) sin(2x)/x )dx
    find the S sin(2x)/x dx . The integral goes from 0 to infinity.

    Note that they are basically asking you to calculate F(0).

    And can you think of a way to write a simple expression for F'(t)? Use that to find F(t).

    Sorry, indeed I figured out how should I find the other integral, but actually I'm having problems integrateing F'(t).

    Sorry to hear that. Maybe if you show what kind of problems, someone could help.
