The textbook for this course is
Interactive
Linear Algebra by Dan Margalit and Joseph Rabinoff.
There is also an optional textbook which is purely
for reference (we do not use it at all anymore in 1553):
Linear Algebra and its Applications, 6th edition, by
Lay–Lay–McDonald, which you can view online if you purchase access to
MyMathLab.
For those who wish to purchase MyMathLab access, you can
follow the instructions
here.
This will also grant MyMathLab access to Thomas' Calculus, Early
Transcendentals, which most students will use later, so
you may find it convenient to purchase the code even though it is not
required for Math 1553. If you have previously purchased MyMathLab
access to these textbooks at Georgia Tech within the past 18 months,
you should not need to purchase a new code and in this case please see
the final page of the 1553 syllabus for details on how to proceed.
