Fourier Transform Help with Mathematica

Click For Summary
SUMMARY

The discussion centers on using Mathematica for performing Fourier Transform and Inverse Fourier Transform. The user emphasizes the importance of defining a function in terms of the variable ##k## rather than ##x## to correctly compute the inverse Fourier transform to obtain ##f(x)##. Additionally, it is crucial to note that the variable ##b## should be multiplied by ##k##, not by the absolute value of ##k##, to ensure accurate results in the transformation process.

PREREQUISITES
  • Understanding of Fourier Transform and Inverse Fourier Transform concepts
  • Familiarity with Mathematica software and its syntax
  • Knowledge of function definitions in mathematical terms
  • Basic grasp of variable manipulation in mathematical equations
NEXT STEPS
  • Explore Mathematica's documentation on Fourier Transform functions
  • Learn how to define functions in Mathematica using the variable ##k##
  • Study examples of Inverse Fourier Transform in Mathematica
  • Investigate the implications of variable manipulation in Fourier analysis
USEFUL FOR

Students and professionals in mathematics, physics, and engineering who are working with Fourier Transforms in Mathematica, particularly those seeking to understand the nuances of variable definitions and transformations.

TL;DR
I am attempting to do a problem involving wave functions and imaginary numbers
I am attempting to be able to do this problem with the help of Mathematica and Fourier transform. My professor gave us instructions for Fourier Transformation and Inverse Fourier, but I don't believe that my output in Mathematica is correct.

You're supposed to define a function of ##k##, not ##x##, and find the inverse Fourier transform to get ##f(x)##. Also, note that ##b## is multiplied by ##k##, not ##\lvert k \rvert##.
