A Group Formula for Derivatives of Higher Order for Product of Five Functions and Determinant Expression
Abstract:This paper studies derivatives of higher order about product of five functions, and obtains a group dependent derivative formulas,and extend the results of relevant papers .At the same time,this paper applies determinant knowledge in algebra to derivative operation in analysis ,and introduces the corresponding symbol, making the corresponding derivative formulas appeare to be guite simple.The original operation will be simplified by using these formulas to find derivatives of higher order for same kind functions, to conduct approximation operation and to give approximation expression.
Keywords: product of five functions derivatives of higher order formula determinant
