GLOSSARY

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. 

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
