1. The problem statement, all variables and given/known data Express the DE as a first order system normal form. Then, express is matrix notation. 2y''+3y'-4ty=1-t^3 I need to transform this into a first order system. I first divided the entire equation by 2 and got y''-(3/2)y'-2ty=(1-t^3)/2 I am not sure what to do now. My first attempt was setting x1=y, x1'=y', and x2=y', x2'=y'' I don't know if I am heading in the right direction and if so, was not sure what to do next.
