全微分 complete differential 如果二元函数z=f(x,y)在P(x,y)点的增量Δz=f(x+Δx,y+Δy)-f(x,y) 能表示为Δz=AΔx+BΔy+0(ρ),其中,A、B,是与Δx和Δy无关的常数,0(ρ)表示当ρ→0时比ρ高阶的无穷小量, 即0(ρ)趋于0的速度比ρ趋于0的速度要快,AΔx+BΔy成为函数增量的主要部分,并且关于Δx、Δy是线性的,则说二元函数z=f(x,y)T赑点可微,称AΔx+BΔy为函数的全微分。记为dz=AΔx+BΔy,因自变量的微分等于改变量,所以dz=Adx+Bdy。与一元函数所不同之处是,在一元函数中,函数在P点可微与可导是等价的,但对二元函数来说,由可微可推出两个偏导数(见偏导数)存在,但光从两个偏导数存在还不能得出可微的结论。 |
