Question

Why we study numerical method? 

Answer 1

Numerical Methods are mathematical way to solve certain problems.

There are many things that you want to compute that can not be computed exactly. The roots of high degree polynomials. The solution of simple differential equations on irregular domains. Any calculation with real numbers that you do with a computer. Also, in many cases, using Numerical Methods we can get really close to the exact answer much quicker than solve analytically.
