These pdf files are a draft of my lecture notes on introduction to numerical analysis. I am providing them here as individual files, and will update them throughout the course. If a file changes - an updated date will show next to it. Since I am compiling every chapter individually, some cross references, may be corrupt. Please report to me any mistakes that you find.
For floating point arithmetic, see: Michael Overton, Numerical Computing with IEEE Floating Point Arithmetic. Maryland has a site license for SIAM books so if you are on campujs or login through a VPN connection, you can read the book and download individual chapters.
