Regarding Q2: m: is user input (make your plots for m = 2 or 3 if like). And take any time domain you like (better t = [0,5] sec).

Also, you can use fplot() or plot() for any question as you like.

Q2: Write a code to calculate and plot the ripples of powers (m) for the following: Given equation, where m is defined by the user and can be any number of powers... u = 21 sin 21+ Find the following: z (1)= udt 0 2 dx W, (s)=L{w(t)} "Laplace" y" - 4y' + 3y =w (0.5) Solve for y (t) using dsolve()" function for zero inital conditions li.e.y(O)=y'(0)=0) Plot the results for (u,z,w,W2,y ) using subplot() function. Note: to avoid MATLAB versions problems, it is better to use "plot() function instead of plot()" for the evaluated symbolic functions, as following: wys EX tt - 010.011 plot itt tatt ihald plotitsubst.tt
