6)

a)

clc%clears screen
clear all%clears history
close all%closes all files
syms y(t)
eq=diff(y,3)-5*diff(y,2)-22*diff(y)+56*y==0;
disp('The solution is')
y(t)=simplify(dsolve(eq))

b)

clc%clears screen
clear all%clears history
close all%closes all files
syms y(t)
eq=t*diff(y,2)+4*diff(y)==t^2;
disp('The solution is')
y(t)=simplify(dsolve(eq))
