Either way, I have no idea. :)
A Theoretical Introduction to Numerical Analysis (Hardcover)
***********************EXCERPT*****************
presents the general methodology and principles of numerical analysis, illustrating the key concepts using numerical methods from real analysis, linear algebra, and differential equations.
***************************
Explains the most fundamental and universal concepts, including error, efficiency, complexity, stability, and convergence. Addresses advance topics, such as intrinsic accuracy limits, saturation of numerical methods by smoothness, and......
Never studied this area of Math,...stayed with Foundations...like Topology...
