differentiation 是微分,是x->0时的增量,一般数学上表示为dy.derivative是微商,是x->0时,dy/dx的比值,又叫导数.一般有y`=f`(x)=dy/dxdy=f`(x)dx derivative和differentiation的区别 differentiation 是洞没隐自变量有一微小变化时,因变量相应发生的变化,一般用dy表示。所以纳厅dy=tanθdx,tanθ是点x切线斜率。
A qualitative or quantitative difference between similar or comparable things. Derivative Lacking originality. Differential (mathematics) An infinitesimal change in a variable, or the result of differentiation. Derivative Something derived. Differential One of two coils of conducting wire so related to one...
Most of us may think that the derivative of the product of two functions is the product of the derivatives, similar to the sum and difference rules. But, the product rule does not work that way. For example, the derivative of f (x)=x2is f’ (x) = 2x and is not $\frac{d}{dx...
9. According to the objective of second-order derivative related to curvatures, it is proved that there is no difference whether we insert a knot or not. And it presents a characteristic of cubic Hermite interpolation curves. 如果以与曲率有关的二阶导数为目标,证明插入节点与不插入节点的情形是一...
Differentiation—i.e., calculating the derivative—seldom requires the use of the basic definition but can instead be accomplished through a knowledge of the three basic derivatives, the use of four rules of operation, and a knowledge of how to manipulate functions. ...
The difference between an ordinary and a partialderivativewas at first not explicitly recongized. 通常的导数与偏导数的区别在一开始并未被人们明确地认识. 辞典例句 Ozone is formed in the reaction, and a nitroderivativeof the olefin. 在反应中形成臭氧及烯烃的硝基衍生物. ...
