A function G(x,y,z) is called homogeneous of degree p if , for all values of the parameter λ,we have the identity F(λx,λy,λz)=λ^pF(x,y,z) (b)Prove that if F(x,y,z) is differentiable and homogeneous of degree p, then F(x,y,z) satisfies x σF/σx + yσF/σy + zσF/σz =pF. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.113.163.95
