Write a user$-$dened function named power$\_$series that approximates the sine function using its

power series expansion:

sin$($x$)=$ x $$

x

$3$

$3!+$

x

$5$

$5!$

x

$7$

$7!+...$

The function should take two input arguments: the value of x and the number of terms in the power

series expansion, n$.$
