Abstract:Numerical methods as an important part of mathematics, more widely applied in life, the same is also playing an increasingly wide range of usefulness.
This article describes some of the numerical method knowledge in practical problems, mainly around the Curve fitting, Interpolation method.
First, fitting the numerical calculation in the practical issues play an important role, mainly to solve the question of the relationship between average income and risk preference and life insurance amount. Second, understanding the definition of the interpolation to solve the height of the atmospheric pressure. Financial accounting the use of numerical calculation of the interpolation method atmospheric pressure, real interest rates of yields and redemption yields instantiated analysis of contact life.
