An implicit function can sometimes be successfully defined as a true function only after "zooming in" on some part of the x-axis and "cutting away" some unwanted function branches. Then an equation expressing y as an implicit function of the other variables can be written. Zobacz więcej In mathematics, an implicit equation is a relation of the form $${\displaystyle R(x_{1},\dots ,x_{n})=0,}$$ where R is a function of several variables (often a polynomial). For example, the implicit equation of the Zobacz więcej Inverse functions A common type of implicit function is an inverse function. Not all functions have a unique inverse … Zobacz więcej In calculus, a method called implicit differentiation makes use of the chain rule to differentiate implicitly defined functions. To differentiate … Zobacz więcej Consider a relation of the form R(x1, …, xn) = 0, where R is a multivariable polynomial. The set of the values of the variables that satisfy this relation is called an implicit curve if n = 2 and an implicit surface if n = 3. The implicit equations are the basis of algebraic geometry Zobacz więcej Not every equation R(x, y) = 0 implies a graph of a single-valued function, the circle equation being one prominent example. Another example is an implicit function given … Zobacz więcej Let R(x, y) be a differentiable function of two variables, and (a, b) be a pair of real numbers such that R(a, b) = 0. If ∂R/∂y ≠ 0, then R(x, y) = 0 defines an implicit function that is … Zobacz więcej The solutions of differential equations generally appear expressed by an implicit function.

If we define the function f(x, y) = x + y , then the equation f(x, y) = 1 cuts out the unit circle as the level set {(x, y) f(x, y) = 1}. There is no way to represent the unit circle as the graph of a function of one variable y = g(x) because for each choice of x ∈ (−1, 1), there are two choices of y, namely . However, it is possible to represent part of the circle as the graph of a functio…
