What Does Undefined Mean In Math Examples

A good real life example of undefined slope is an elevator since an elevator can only move straight up or straight down.

What does undefined mean in math examples. Undefined means there is no answer to the expression at that point. For example in the real number system is undefined for negative. 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. What does undefined mean.

Undefined is a term used when a mathematical result has no meaning. 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. Think of it as the value where you end with more question marks at the end. In arithmetic some arithmetic operations are called undefined.

The term can take on several different meanings depending on the context. 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. An expression in mathematics which does not have meaning and so which is not assigned an interpretation. In our time we can say that 5 8 is undefined in the set of positive integers.

The most famous example is that division by zero is undefined. 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. More precisely undefined values occur when an expression is evaluated for input values outside of its domain.

Sqrt 9 if no complex numbers ln 4 if no complex numbers. However something that is undefined today may be given a definition in the future. In plain language it means something which has no sensible meaning. For instance during the time when the negative numbers were not yet invented the numerical expression 5 8 has no meaning.

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