Jim's .ipynb solution to the homework is attached.
We saw that dot products *are* the fourier transform ... at least when you're using the right "orthonormal basis" of oscillating vectors.
Changing a vector from the 4-component "T" basis to the oscillating "F" basis is in fact a Fourier Transform. And the dot product does that for you.
Assignment :
- Review my posted solutions.
- Do the last exercise - the transform - for a different "randomly chosen" vector.
- Generate plots for that vector and it's transform.
- Read about "matrix multiplication". We'll talk about that next week.
