Chronological list of essential material from e-mails:
It will include comments on the Syllabus, material on interpreting the book, and problems with pages from the book discussed in class. It does not replace material in class which will sometimes – for efficiency – rearrange book material.
✺
Class01-23-19Lines-Planes
: Based on combining the presentation of
Lines in the Curriculum
with material from the book.
What the book is calling a vector.
Matrix multiplication: We have only used it to turn a matrix into a function by using a vector as a 1-column matrix.
Heading toward changing a non-row reduced matrix into reduced echelon form, using the key words: row reduction, span, linear independent vectors.

LinesCurriculum2019:
At every stage in mathematics, lines are important, but that doesn't prepare us for the big jump to
parametrized
lines in, say,
R
3
, 3-space. It is this parametric line that we expect to get as the solution set for two linear equations in 3 unknowns.
