摘要
用求条件极值的拉格朗日乘数法及极限的理论,把三维欧几里得空间中原点到平面的距离公式推广到n维(n>3)的l_p(p≥1),l_∞等赋范线性间中。
By the lagrange multiplier method for solving maximum- minimum problems and by the theory of limitsthis article applied the formuld for the distance from origin tothe generaliyation—plane in the three dimensional Euclid Spaceto n (n≥3) dimensional l_p and l_∞ spaces.
