GLOSSARY

Accuracy: truthfulness and certainly of a value.

Approximation: Estimation or inexact representation of a value. An approximation is a quantity that represents a desider value.

Analytical solution: Mathematical exppression that represent a system. Gives a real result. 


Gauss: Carl Friedrich Gauss. (1777-1885) German scientist and mathematician. He studied numerical methods, statistics, geometry, physics, astronomy, optics, and others.

Mathematical Model: formulation that expresses a physical phenomena or system in mathematical terms. 

Method:technic for doing something.

Numerical method: “techniques by which mathematical problems are formulated so that they can be solved with arithmetic operations.” Steven Chapra

Numerical solution: Approximation  to the result of a system.

  

Parameters: compounds of a model.

Significant digits: digit(s) that gives confidence to a number.

Total numerical error: is the summation of the truncation and round-off error.

Truncation error: “is the discrepancy introduced but the fact that numerical methods may employ approximations to represent exact mathematical operations and quantities” Steven Chapra

Vector: Vertical arrengement of numbers. It represents a serie of values.
