Is a number divided by 0 undefined?
Don’t divide by zero or this could happen! Just kidding. In truth: Dividing by Zero is undefined.
What does it mean when an equation is undefined?
We learned that a numerical expression is undefined when there is no answer or when you get division by zero. We might get division by zero for those numerical expressions with variables and a denominator. To find the points where the numerical expression is undefined, we set the denominator equal to zero and solve.
Is undefined the same as 0 Javascript?
Now x will be set to 0 if it was either null or undefined , but not any other value. You can use undefined in the test too. It’s exactly the same.
What is the difference between undefined and no solution?
If something is undefined in mathematics, that just means that there’s no object/operation in the system we’re working in that has a given property. If an equation or system of equations has no solution, that means there’s no object in the relevant system that satisfies the equation(s).
Does undefined mean the limit does not exist?
The answer to your question is that the limit is undefined if the limit does not exist as described by this technical definition. In this example the limit of f(x), as x approaches zero, does not exist since, as x approaches zero, the values of the function get large without bound.
Why undefined is false?
3 Answers. In javascript strict mode, undefined is not false, but javascript try to convert the object or var to a boolean value (this is called in javascript truthy value), that’s the reason you got an undefined as false. This happens with null also, for example.
Is the value of 0/0 undefined?
So 0/0 must be undefined. Also, if you think about it more closely, (Sal also says this in the next video.) division must be able to be undone by multiplication. For example, 6 divided by 2 is 3, and it can be undone by multiplying 2 by 3 to get 6. If 0/0 is 1, then 1 times 0 is , so it is correct.
Is 1/0 indeterminate or undefined?
Here is what we mean by “indeterminate.”. The value of 1/0 is called “undefined” because there is NO number x that satisfies the equation 1/0 = x, or equivalently, 0*x = 1. In contrast, EVERY number x satisfies the equation 0/0 = x, or equivalently, 0*x = 0.
What is 0/0 divided by 1?
One can argue that 0/0 is 0, because 0 divided by anything is 0. Another one can argue that 0/0 is 1, because anything divided by itself is 1. And that’s exactly the problem!
What is the value of 0/0 =?
0/0 = 1 ==> 0 * 1 = 0. Oops, that also works. and so does 0/0 = 2 and 0/0 = 6 and 0/0 = any real number. This is where it breaks down.
