英文:In this math problem, the value of x is undefined. 中文:由于缺少必要的参数,这个函数返回了一个未定义的结果。英文:Due to the lack of necessary parameters, this function returned an undefined result. 中文:这个术语在当前的上下文中是未定义的,我们需要更多的信息来...
This is the solution, which is to say that in this case the k at which the minima appeared cannot be expressed as an algebraic number, but is a particular root of a polynomial. If you want to know the approximate location, you can vpa() the value. 댓글을 달려면 로그...
John was working on a math problem, but he encountered a variable that was undefined. He couldn't solve the problem without knowing its value, so he decided to ask his teacher for help. (约翰正在做一道数学题,但他遇到了一个未定义的变量。他不知道这个变量的值,就无法解决问题,于是他决定向老...
The initial value of undefined is the primitive value undefined. In modern browsers (JavaScript 1.8.5 / Firefox 4+), undefined is a non-configurable, non-writable property per the ECMAScript 5 specification. Even when this is not the case, avoid overriding it. A variable that has not been...
Identify the math term described. Less than zero; minus. Determine the values of x for which the expression is undefined. \frac{1}{2x^2 - 50} 1. What happens to the value of \ln (x) as x approaches zero? What does zero measure mean? Why is \tan(\frac{\pi}{2})}] undefined ...
