Consider the function: f(x, y)=\left\{\begin{matrix} \frac{k(x^2+y^2)}{\sqrt{x^2+y^2+1}-1}, if (x,y)\neq (0,0)\\ 1, if (x,y)=(0,0)\\ \end{matrix}\right. where k is a constant. Does the function have ...
(f(x)) is a linear function and is a constant. Under which of the following conditions is the slope of (f(x)) greater than the slope of (f(rx))? ()Ⅰ. (f(x)) is ascending and < 1Ⅱ. (f(x)) is descending and 0≤ < 1Ⅲ. (f(x)) is descending and > 1A. Ⅰ only...
If f is a constant function, f(x,y)=k and R=[a,b]* [c,d], show that \iint\limits_{R}k\d A=k(b-a)(d-c) 相关知识点: 试题来源: 解析 If we divide R into mn subrectangles, \iint _{R}k\d A\approx\sum\limits _{i=1}^{m}\sum\limits _{j=1}^{n}f(x^{*}...

The graph of a function that has a constant output regardless of the input is called a ___ function. A. constant B. identity C. reciprocal D. logarithmic 相关知识点: 试题来源: 解析 A。本题考查函数的分类。选项 A“constant”表示常量函数,输出恒定;选项 B“identity”是恒等函数;选项 C“reci...
error: #59: function call is not allowed in a constant expression This is an similar example of the code: const sam_abc xy_settings = {function_yz(), 111, 250 }; - sam_abc is a struct - function_yz() is the function which causes the error ...
We review the observational information on the constancy of the fine structure constant \\\(\\\alpha\\\) . We find that small improvements on the measurement of 187 Re lifetime can provide significant progress in exploring the range of variability suggested by QSO data. We also discuss the ...
