&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;In [[mathematics]], a '''functional equation''' is any [[equation]] that specifies a [[Function (mathematics)|function]] in [[Implicit function|implicit form]].&lt;br /&gt;
&lt;br /&gt;
== Description ==&lt;br /&gt;
&lt;br /&gt;
Often, the equation relates the value of a function (or functions) at some point with its values at other points.&lt;br /&gt;
&lt;br /&gt;
For instance, properties of functions can be determined by considering the types of functional equations they satisfy.&lt;br /&gt;
&lt;br /&gt;
The term functional equation usually refers to equations that cannot be simply reduced to algebraic equations.&lt;br /&gt;
