...偏导数是一类特殊的方向导数。 Derivative of a vector-valued function f can be defined as the limit wherever it exists finitely. As mentioned before, this gives us the rate of increase of the function f along the direction of the vector u. In the case of a single-valued function, this r...

...? 答案 超级用户贡献者mtone为我们提供了答案: If a VBA function is called from several formulas or if your script generates or forces the recalculation of several formulas, then this should definitely make use of the multi-threaded calculation feature in Microsoft Excel. Respectiv...
功能与程序 计算机编程是软件开发过程的一个阶段。它被认为是一门手艺、一门艺术和一门工程学科,可以为计算机用户遇到的问题创建一个有用的软件解决方案。在编写计算机程序时,程序员使用一种程序设计语言。程序设...
...包含导数,而导数实际上指定了一个量相对于另一个量是如何变化的。通过解一个微分方程,你得到一个不含导数的量的公式。计算导数的方法叫做微分法。简单地说,函数的导数是输出值相对于输入值的变化率,而微分是函数...
什么是二次函数(a quadratic function)? 二次多项式函数称为二次函数。形式上,f(x)=ax2+bx+c是一个二次函数,其中a、b和c是实常数,a≠x的所有值均为0。二次函数的图形是抛物线。 如何求二次函数的对称轴 任何二次函数...
...移为1m,则功为1焦耳。 If the force is not c***tant but rather a function of position , then the work done by the force to move the object from a position to another position is given by, So if a force vs. distance graph is drawn, the work done to move the object from to is equal t...
...。微分表示像物体面积一样可变的量的最小差别。它可以计算方程中自变量和因变量之间的关系。比较参数差异衍生品定义微分表示变量量的最小差异。导数表示微分方程中变量的变化率。计算的差异计算线性差。图在特定点的...
