Learning Resources

This module is populated from the local chunked books in library/raw/semester-01-math-foundations/books. Use this page as a source map, not as an instruction to read everything.

Exercise Support Chunks​

Use these after the concept pages are understood but your fluency is weak:

Use Rules​

  • If you are stuck on structure, go to Linear Algebra and Its Applications first.
  • If recurrence behavior is the gap, use the MCS recurrence chunk only as a second pass.
  • Open one chunk for one concept gap; do not start reading whole chapters by default.
  • If rereading does not help, stop and explain the matrix in terms of spaces, directions, and approximation before opening another chunk.
