$7.$ Create a vector x with the elements,

$x_n=$

$((1)^($n$+1))/(2$n$1)$

$,$ where n$=\{1,2,3,...,100\}$

Then, add up the elements of the version of this vector that has $100$ elements

$8.$ Make multi plots for the following two functions in one figure as shown below. Do not forget to add

the axis labels, a title, and grid.

f$1($x$)=$ sin$(1/$x$)$ for $0\mathrm{.}01<$ x $<0\mathrm{.}1.$

f$2($x$)=$ cos$(1/$x$)$ for $0\mathrm{.}01<$ x $<0\mathrm{.}1.$

$[$Code Hint$]$:

figure

subplot$(2,2,1)$;

$$ Add your code for plotting the sin$(1/$x$)$ function

subplot$(2,2,2)$;

$$ Add your code for plotting the cos$(1/$x$)$ function

subplot$(2,2,3$:$4)$;

$$ Add your code for plotting the two functions together $($use $$hold on$)$

$13.$ Write a script that asks for a temperature $($in degrees Fahrenheit$)$ and computes the equivalent

temperature in degrees Celsius. The script should keep running until no number is provided to convert.

$[$Note: the function isempty will be useful here.$]$
