One of them is a cubic polynomial (with argument cos(x)) and the second one is the function, that assures monotonous falling of the function. Usage of this approach leads to considerable reduce of the approximation error and increases accuracy of the object's highlights representation.关键词: ...
Homogeneous potential of degree −3Polynomial integrabilityIn this paper, we study the polynomial integrability of natural Hamiltonian systems with two degrees of freedom having a homogeneous potential of degree k given either by a polynomial, or by an inverse of a polynomial. For k = − 2 ,...
摘要: In this article by elementary method we have proved neccessary and sufficient conditions for a polynomial of degree 3 or 4 with real coefficients to be a von Neumann polynomial. These conditions are convenient for application.被引量: 6 ...

解析 F(x)=(x-2)(x+3)+(ax+b)When ax+b is dvided by x-2,the remainder must be 1,and this gives usax+b=a(x-2)+1 (1)Similarly we also haveax+b=a(x+3)+6 (2)(1) and (2) gives us a=-1 and b=3.反馈 收藏 ...
