What Does Undefined Mean In Math Examples

Undefined means there is no answer to the expression at that point.

What does undefined mean in math examples.

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. Undefined is a term used when a mathematical result has no meaning. In our time we can say that 5 8 is undefined in the set of positive integers. 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.

For example in the real number system is undefined for negative. 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. An expression in mathematics which does not have meaning and so which is not assigned an interpretation. More precisely undefined values occur when an expression is evaluated for input values outside of its domain.

In arithmetic some arithmetic operations are called 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. Sqrt 9 if no complex numbers ln 4 if no complex numbers. Ambiguous complex infinity directed infinity division by zero ill defined indeterminate well defined.

For example square root of a negative number was undefined. However something that is undefined today may be given a definition in the future. It got its name undefined from the fact that it is impossible to divide by zero. For example division by zero is undefined in the field of real numbers.

Think of it as the value where you end with more question marks at the end. What does undefined mean. In plain language it means something which has no sensible meaning. 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.

In algebra a function is said to be undefined at points not in its domain. The most famous example is that division by zero is undefined.
