Write a Python script to plot waves of similar frequencies and their sum.

a$.$ Add a new feature: User$-$input values.

input$("$enter first frequency in $Hz$: $)$

print$("$first frequency is:$",$f$1)$

f$2=$ int$($input$("$enter second frequency in $Hz$: $)$

print$("$second frequency is:$",$f$2)$

b$.$ In your script, define your start and end times as tstart and tend and a time array.

#define functions to plot frequenciesc. Define two functions as y$1=$sin$(2$pif$\_(1)$t$)$ and y$2=$sin$(2$pif$\_(2)$t$)$d$.$ Define a new function y sum $=$y$1+$y$2.$e$.$ Plot two similar frequencies and their sum, showing a "beating" pattern. $($try$,$ for example, f$1=250,$f$2=257,$ tstart $=-\mathrm{.}1,$ tend $=\mathrm{.}1)$f$.$ Calculate the carrier and modulation frequencies for part c either by hand or in your program,g$.$ Hand in your script $($copy and paste into a word or pdf file$),$ results, and your plots $($image files or in a word or pdf file$).$
