Pre-Lecture Notes from University Notes

• Recall past definitions:
  • Kronecker Delta.
  • Alternating Tensor.
  • Suffix Notation.
  • Gradient.
  • Divergence.
  • Curl.
• Then, just further definitions, like the position vector and its magnitude (same as normal), then exploring its relationships with the aforementioned definitions.
• Combining differential operators to get things like div grad, curl grade, grad div, div curl, and curl, finding them all
