What does undefined mean.
What does undefined mean in math examples.
For instance during the time when the negative numbers were not yet invented the numerical expression 5 8 has no meaning.
More precisely undefined values occur when an expression is evaluated for input values outside of its domain.
For example in the equation ax by c the relation between x and y is indeterminate because you can t determine it without knowing the values of a b and c.
Sqrt 9 if no complex numbers ln 4 if no complex numbers.
In arithmetic some arithmetic operations are called undefined.
In our time we can say that 5 8 is undefined in the set of positive integers.
For example square root of a negative number was undefined.
Broadly speaking undefined means there is no possible value or there are infinite possible values while indeterminate means there is no value given the current information.
It got its name undefined from the fact that it is impossible to divide by zero.
However something that is undefined today may be given a definition in the future.
For example in the real number system is undefined for negative.
January 2015 in mathematics the term undefined is often used to refer to an expression which is not assigned an interpretation or a value such as an indeterminate form which has the propensity of assuming different values.
Undefined is a term used when a mathematical result has no meaning.
The most famous example is that division by zero is undefined.
In algebra a function is said to be undefined at points not in its domain.
Mathematically undefined can be defined as an expression which is impossible or an expression which does not have an exact definition or an expression that cannot be interpreted.
Undefined means there is no answer to the expression at that point.
Think of it as the value where you end with more question marks at the end.
The term can take on several different meanings depending on the context.
For example division by zero is undefined in the field of real numbers.
A good real life example of undefined slope is an elevator since an elevator can only move straight up or straight down.
Recall that 6 2 equal 3 because 3 2 6 however it is impossible to do 5 0 because there exist no number you can multiply 0 by to get 5.
