Please solve it using python and provide the code $6\mathrm{.}4$ Determine the lowest positive root of $f(x)=$

$7sin(x)e^{-x}-1$ :

$($a$)$ Graphically.

$($b$)$ Using the Newton$-$Raphson method $($three iterations,

$x_i=0\mathrm{.}3).$

$($c$)$ Using the secant method $($three iterations, $x_{i-1}=0\mathrm{.}5$

and $x_i=0\mathrm{.}4.$

$($d$)$ Using the modified secant method $($five iterations,

$\{$:$x_i=0\mathrm{.}3,=0\mathrm{.}01).$
