Problem$-7(10$ Points$)$: Programming in MATLAB $($there are two parts, 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$)$:

$7$a$.$ Plot the function, $y=10sin\frac{x}{x}$ for the range $1x10$ using a$)$ fplot and b$)$ "for" loop function. Have both the plots on the same graph. Refer example$-1$ in manual.

$7$b$.$ Refer Problem$-1/$ part$-1.$ Using ode$45$ function, solve the first order ODE and plot $y(t)$ for $0t5$ seconds. Use time steps $=0\mathrm{.}001$ seconds and $y(0)=0.$ Refer example$-2$ in manual.
