22. In this exercise, we explore the connections between the method of integrating fac-\tors discussed in this section and the Extended Linearity Principle. Consider the\nonhomogeneous linear equation\\ $\frac{dy}{dt} = a(t)y + b(t)$,\where $a(t)$ and $b(t)$ are continuous for all $t$.\(a) Let\$\mu(t) = e^{-\int_0^t a(x)dx}$.\\Show that $\mu(t)$ is an integrating factor for the nonhomogeneous equation.\(b) Show that $1/\mu(t)$ is a solution to the associated homogeneous equation.\(c) Show that\\$y_p(t) = \frac{1}{\mu(t)} \int_0^t \mu(\tau)b(\tau)d\tau$\is a solution to the nonhomogeneous equation.\(d) Use the Extended Linearity Principle to find the general solution of the nonho-\mogeneous equation.\(e) Compare your result in part (d) to the formula\\$y(t) = \frac{1}{\mu(t)} \int \mu(t)b(t)dt$\for the general solution that we obtained on page 126.\(f) Illustrate the calculations that you did in this exercise for the example\$\frac{dy}{dt} = -2ty + 4e^{-t^2}$.

6.23 A unit is composed of two components in series where Î»â‚ = 0.87 and Î»â‚‚ = 1.46 are their respective failure rates. For two identical units with one in standby and assuming no failures in standby and perfect switching, find R(2) and the MTTF. If the two components, A and B, can be configured in a low-level redundancy with one A and one B in standby, find R(2) and the MTTF.
