Programming in MATLAB $($there are two parts, $8$a and $8$b$,$ each worth $5$ points$).$ NOTE:

Throughout the semester, whenever you generate plot$($s$)$ in MATLAB, please include appropriate x$,$ y label,

title and legend $($if needed$).$ You must submit the mfile, answers from the command window, and figure$($s$).$

One way to do this is to copy your code, figures and answers from command window and paste it on a word

document. Then scan this document along with the rest of your work.

$8$a$.$ Plot the function, y $=10$cos$($x$)/$x for the range $1<=$ x $<=10$ using a$)$ fplot and b$)$for$$ loop function. Have both

the plots on the same graph. Refer example$-1$ in manual.

$8$b$.$ Refer Problem$-1/$ part$-1.$ Using ode$45$ function, solve the first order ODE and plot y$($t$)$ for $0<=$ t $<=5$ seconds.

Use time steps $=0\mathrm{.}001$ seconds and y$(0)=0.$ Refer example$-2$ in manual.
