What is called when the denominator is zero in a rational function?
The function is not defined at any values at which the denominator is zero.
Are numbers that can be written as the ratio of two integers in which the denominator is not zero called reciprocals?
No, they are not!
If zero divided by zero is undefined then how is zero divided by a whole number is zero?
if there is 0 in the numerator it is zero regardless. But if it's zero in the denominator and zero in the numerator then it is undefined in all such cases where the denominator equals zero.
If a fraction has - in the denominator it is undefined?
The answer depends on the part of the question that is missing.
What is the denominator of a zero slope?
It is any non-zero number.
What is called when the denominator is zero in a rational function?
The function is not defined at any values at which the denominator is zero.
When the denominator is zero in a rational function what is that called?
Undefined.
When checking solutions if a solution makes the denominator zero it is called what?
It may be called a singularity.
Why do singular points arise in a differential equation?
The most common reason is because zero appeears in the denominator. Since zero in the denominator is undefined, any point where zero appears in the denominator is called a singularity. A lot of math and physics is done to get around singularities.
What number can not be a denominator?
zero can not be a denominator.
Are numbers that can be written as the ratio of two integers in which the denominator is not zero called reciprocals?
No, they are not!
What can't you have in the denominator?
A zero. Zero in the denominator make the expression undefined for algebraic purposes.
What can a denominator not be?
Zero
If a fraction in the denominator it is undefined IT HAS WHAT its denominate?
a value of zero in the denominator makes the fraction undefined
If a fraction in the denominator it is undefined IT HAS WHAT?
If the denominator has a zero value.
If zero divided by zero is undefined then how is zero divided by a whole number is zero?
if there is 0 in the numerator it is zero regardless. But if it's zero in the denominator and zero in the numerator then it is undefined in all such cases where the denominator equals zero.
