$1.$ Develop a MATLAM function named $$rectangular$($R$,\backslash$theta $)$ to convert a given polar coordinate to rectangular coordinate using the following expressions,

X $=$ R$*$cos$(\backslash$theta $),$ Y $=$ R$*$sin$(\backslash$theta $)$

Where R is the radius, and $\backslash$theta is the angle in degree with the positive x$-$axis. R and $\backslash$theta also can also be vectors., which means you should use element$-$by$-$element multiplications.

Use fprintf$()$or disp$()$ statement Inside the function to output the result as $($X$+$Yi$)$

If you run the function rectangular$()$ from the command window you will get the following result.
