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

$sin(x)=x-\frac{x^3}{3!}+\frac{x^5}{5!}-\frac{x^7}{7!}+$dots

The function should take two input arguments: the value of $x$ and the number of terms in the power series expansion, $n.$In Matlab
