This calculator uses numerical differentiation to calculate the first derivative $f'(x)$.

Given,

$y=f(x)=$

Initial guess $x_0 =$

Error threshold$(e)=$

Solution,

$n$	$x_n$	$x_{n+1}$
$2$	$1.000$	$1.333$
$3$	$1.333$	$1.264$
$4$	$1.264$	$1.260$
$5$	$1.260$	$1.260$

Therefore, the solution is at $1.260$
