The required partial derivatives are easily worked out . 欲求的偏導(dǎo)數(shù)不難得出。
We will replace the partial derivative by an ordinary derivative . 我們可用普通微商代替偏微商。
The method set out above for computing partial derivatives is often used in economics . 上面建立的計算偏導(dǎo)數(shù)的方法經(jīng)常用在經(jīng)濟學(xué)中。
The difference between an ordinary and a partial derivative was at first not explicitly recognized . 通常的導(dǎo)數(shù)與偏導(dǎo)數(shù)的區(qū)別在一開始并未被人們明確地認識。
Study on differences of two definitions of partial derivative 偏導(dǎo)數(shù)兩種定義的差異研究
the derivative of a function of two or more variables with respect to a single variable while the other variables are considered to be constant 同義詞:partial
In mathematics, a partial derivative of a function of several variables is its derivative with respect to one of those variables, with the others held constant (as opposed to the total derivative, in which all variables are allowed to vary). Partial derivatives are used in vector calculus and differential geometry.
