(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≤ <
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 ...
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^{*}...

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 ...

Definition of a periodic function : For a function to be periodic, having a non-zero constant p, it should satisfy its definition : f(x+p) = f(x) This is the periodic function formula If this property is satisfied by any positive constant p, it is referred to as the fundamental per...
