a. Show that the solution of the general linear equation can be written in the form
y=cy1(t) +y2(t), where c is an arbitrary constant.
b. Show that y1 is a solution of the differential equation y' + P(t)y= 0.
corresponding to g(t)= o
c. Show that y2 is a solution of the full linear equation (1). We see later (for example, in Section 3.5) that solutions of higher- order linear equations have a pattern similar to equation
