Also known as implicit equation
function defined by a relation of the form 𝑅(𝑥,𝑦)=0, where 𝑅 is a function of several variables and there is a unique 𝑦 that satisfies the relation for every 𝑥

在數學中，隱式方程（英語：Implicit equation）是形同的關係，其中是多元函數。比如單位圓的隱式方程是。 隱函数（implicit function）是由隱式方程所隱含定義的函數，比如是由確定的函數。而可以直接用含自变量的算式表示的函数称为显函数，也就是通常所说的函数，如。 隱函數定理說明了隱式方程在什麼情況下會確定出隱函數。
