FEM2D

Numerical analysis continues this long tradition of practical mathematical calculations. Much like the Babylonian approximation of sqrt{2}, modern numerical analysis does not seek exact answers, because exact answers are often impossible to obtain in practice. Instead, much of numerical analysis is concerned with obtaining approximate solutions while maintaining reasonable bounds on errors.
