Create a function to numerically integrate the equation using the Rectangle Method $($mid point$),$ I$=(2)/((()\backslash$pi $))\_$a$^$b xe$^(-$x$^(2))$ The input would be in the sequence, a$,$b $,$ and n $.$ Name the function "rectangle$\_$method $($a$,$b$,$n$)".$ The $"$ n $"$ is the number of rectangles. Note: Do not call the function at the end of the script. The function should only output one value; suppress all other outputs. Answer: $($penalty regime: $0$
