摘要
讨论了二元函数微分中值定理的“中间点”当点B(x0+Δx,y0+Δy)沿直线段AB向点A(x0,y0)逼近时的渐近性质,获得了在较弱条件下的渐近估计式。
By discussing the asymptoticality of the medial point in the meanvalue theorem for derivatives of two variable functions when point B(x0+Δx, y0+Δy)approaches point A(x0,y0)along line segment AB.the asymptotic estimation formulas are obtained under weaker conditions.
