This category contains pages concerning Derivative of Inverse Function:


Let $I = \closedint a b$ and $J = \closedint c d$ be closed real intervals.

Let $I^o = \openint a b$ and $J^o = \openint c d$ be the corresponding open real intervals.


Let $f: I \to J$ be a real function which is continuous on $I$ and differentiable on $I^o$ such that $J = f \sqbrk I$.

Let either:

$\forall x \in I^o: D \map f x > 0$

or:

$\forall x \in I^o: D \map f x < 0$


Then:

$f^{-1}: J \to I$ exists and is continuous on $J$
$f^{-1}$ is differentiable on $J^o$
$\forall y \in J^o: D \map {f^{-1} } y = \dfrac 1 {D \map f x}$
