Implicit Function

It can be defined as:

 If x and y are so mixed up and y cannot be expressed in terms of independent variable x then y  is called an implicit function of x.

Examples:

  1. x^2 + xy+y^2=2
  2. \frac{xy^2-y+9}{xy^2}=12

 

 

Symbolically implicit function is written as  f (x,y)=0
