What does undefined mean.

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. An expression in mathematics which does not have meaning and so which is not assigned an interpretation. Sqrt 9 if no complex numbers ln 4 if no complex numbers. Think of it as the value where you end with more question marks at the end.

In arithmetic some arithmetic operations are called undefined. Ambiguous complex infinity directed infinity division by zero ill defined indeterminate well defined. For example square root of a negative number was undefined. Undefined is a term used when a mathematical result has no meaning.

A good real life example of undefined slope is an elevator since an elevator can only move straight up or straight down. In our time we can say that 5 8 is undefined in the set of positive integers. For example division by zero is undefined in the field of real numbers. 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.

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. In algebra a function is said to be undefined at points not in its domain. 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.

The most famous example is that division by zero is undefined. For instance during the time when the negative numbers were not yet invented the numerical expression 5 8 has no meaning. In plain language it means something which has no sensible meaning. The term can take on several different meanings depending on the context.

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. 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.
