Try these first

1. 1.

   What does the Fourier Integral Theorem allow us to do?

   Hint

   Think about how we analyze functions.

2. 2.

   Define a piecewise continuous function.

   Hint

   Focus on continuity in parts.

3. 3.

   What does the Fourier Integral Theorem represent?

   • Non-periodic functions as sums of exponentials
   • Non-periodic functions as sums of polynomials
   • Non-periodic functions as integrals of sine and cosine

   Hint

   Think about how these functions can be analyzed.

4. 4.

   True or False: The Fourier transform can be applied to any function.

   • True
   • False

   Hint

   Recall the conditions for applying the Fourier transform.

5. 5.

   How would you apply the Fourier Integral Theorem to analyze the response of a structure under a complex loading scenario?

   Hint

   Consider breaking the loading function into manageable parts.

6. 6.

   Derive the Fourier transform for a given piecewise linear function from -1 to 1 and analyze its convergence.

   Hint

   Work through the integral step by step.
