Consider the two-mass, three-spring system of Example 2.Instead of solving the system of four first order equations, we indicate here how to proceed directly from the system of two second order equations given in Eq.(18) of section 6.1.
(a) Show that using the parameter values of Example 2,
(b) Assume that
Note that
(c) Find the eigenvalues and eigenvectors of
(d) Write down the expressions for
(e) By differentiating the result from part (d), write down expressions for

- Find a system of two equations in three variables, x1, x2 and x3 that has the solution set given by the parametric representation x1=t, x2=s and x3=3+st, where s and t are any real numbers. Then show that the solutions to the system can also be written as x1=3+st,x2=s and x3=t.arrow_forwardConsider the system of linear equations in x and y. ax+by=ecx+dy=f Under what conditions will the system have exactly one solution?arrow_forward
