What are some good Numerical Analysis textbooks? I have been doing some research lately about numerical analysis textbooks, but I have not found anything successfully. I was wondering if there is like some sort of standard, for example, whenever someone mentions Calculus, I would think of Spivak or Stewart. I do not have any background nor experience on the subject, so readability counts, and I am a first year undergraduate student. Hopefully I made my point.
Recommendations for Numerical Analysis texts? I'm in a numerical analysis course right now and it's pretty rigorous but I'm enjoying it a lot. I took a lower level course before that was more oriented towards implementation of numerical methods, so it's not my first time with the material.  Anyway, my professor wrote his own course notes and they're fantastic but I wanted some reference material since I'm currently outlining my own notes. Just wondering what the big ones out there are  edit: I would say I'm at an advanced undergraduate level
Prerequisites for classical mechanics by Susskind So I am an undergraduate in Electrical Engineering. We had a course on Physics in our freshman year which is equivalent to Classical Mechanics I as taught in MIT. I am interested in studying advanced classical mechanics (which includes Lagrangian formulation and other stuff) as equivalent to Classical Mechanics lecture by Susskind. I wanted to know are they any prerequisites which I should know about before taking this course.   In general what are the prereqs for this course?
