first day of class and I"m trying to be on top of things by doing my homework....now I dont know how to do the very first problem.
verify by substituion that each given equation is a solution of the given differential equation...
y'' = 9y; y1 = e^(3x); y2 = e^(-3x).
now, exactly what is it asking me to do?
is it just 2 problems where y" = y1 and y" = y2 and just solve it?
