Tangent Line

Enter the function $f\left(x\right)$ and $x_0$, the abscissa of the point at which the tangent line will be constructed:

$f\left(x\right)\=$       

$x_0\=$   (Default value: $x_0\=0$)

$f\prime \left(x\right)\=$

$m\=f\prime \left(x_0\right)\=$

$y_0\=f\left(x_0\right)\=$

$y\=m\left(x-x_0\right)\+y_0\=$
