Differentiation of Implicit Functions
If an equation is expressed as y = f(x), then y is said to be the explicit function of x. However if y is connected with x by an expression f (x, y) = 0, then y is said to an implicit function of x. For e.g. x
^{2}
+ 3xy + y
^{2}
= 0.
For differentiating the implicit function we differentiate each term with respect to x keeping in mind that if there is a term contains powers of y, we differentiate first with respect to y and then multiply it by
dy/dx
to get its differentiation with respect to x.
Example 1:
Example 2:
Calculate
dy/dx

Differentiating both side of equation with respect to x, and using
The Sum Rule
:
Now using
