Numerical Methods Tutorials

What is Numerical Method?

• In reality,“Solving a math problem” generally involves finding an answer rather than exact answer.
• Numerical analysis is the study of algorithms that use numerical approximation for the problems of mathematical analysis.
• A numerical method is a complete and definite set of procedures for the solution of a problem, together with computable error estimates. The study and implementation of such methods is the field of numerical analysis / numerical methods.
• A trick that lets you get closer and closer to an exact answer is a “numerical method”.
• Numerical methods find solutions close to the answer without ever knowing what that answer is. As such, an important part of every numerical method is a proof that it works.
