hello,
I am going through the first chapter (a review chapter) of a second-course book in ODEs, and can't seem to remember how to re-write higher order DEs into a system of first order linear ODEs, and my old textbook only shows this for second order equations...
The question is: "Write the following differential equations as a system of first order ODEs:
y'' -5y'+6y=0
-y''-2y' = 7cos(y')
y(4) - y'' + 8y' + y2 = ex "
