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 ...
An exponential function is a function with the general form f(x) = y = abx and the following conditions:x (input value) is a real number a is a constant and a is not equal to zero (a ≠ 0) b is bigger than zero (b > 0)...
a forward declaration is an identifier declaration (such as a class, function, or variable) to inform the compiler about its existence before it is defined. this allows you to use the identifier in situations where the order of declaration matters. can i declare a constant pointer in c? yes...
Jason has taught both College and High School Mathematics and holds a Master's Degree in Math Education. Cite this lesson In math, a constant is a number and all numbers are constants because the value of individual numbers cannot change. Explore a definition of mathematical constants and rela...
There are a few cases in FreeBSD where the expression (1 << 31) is used. However this produces undefined behavior as '1' is of type int. (see 6.4.4p5: The type of an unmarked integer constant is the first of the following list in which its value can be represented: int, long in...
根据第四段第一句中的" ‘Irregardless' is too a word;you just don't understand dictionaries.(Irregardless也是个单词,只是你不懂得字典)"和最后一段中的第一句"The dictionary's recognition doesn't enroll a word as correct in the English language.(字典的认知并没有将一个单登记为正确的)"可推知,...
What Is a Constant? Imagine that you are writing a program to calculate the area and the circumference of a circle. The formulas are area = pi * radius * radius; circumference = 2 * pi * radius In these formulas, pi is a constant of value 22 / 7. You don’t want the value of ...
What values of k makes the following function continuous? \left\{\begin{matrix} \frac{\sin(-6x)}{9x}& x less than 0\3x-9k-6& x\ greater than equal 0 \end{matrix}\right. For what value of the consta...
Consider the constant {eq}c {/eq} and function {eq}f {/eq}. For what values of the constant would the function be continuous on {eq}(-\infty , \infty ) {/eq}? {eq}f(x)=\left\{\begin{matrix} cx^{2}+2x & x< 2\\ x^{3}-cx & x\geq 2...
