Derivative of Inverse Function: Also presented as
When Leibniz's notation for derivatives $\paren {\dfrac {\d y} {\d x} }$ is being used, Derivative of Inverse Function is usually seen presented as:


 * $\dfrac {\d x} {\d y} = \dfrac 1 {\frac {\d y} {\d x} }$

or:
 * $\dfrac {\d x} {\d y} = \dfrac 1 {\d y / \d x}$

where:
 * $\dfrac {\d x} {\d y}$ is the derivative of $x$ $y$
 * $\dfrac {\d y} {\d x}$ is the derivative of $y$ $x$.

This must not be interpreted to mean that derivative can be treated as fractions; it is simply a convenient notation.
