2 ORDINARY DIFFERENTIAL EQUATIONS FOR ENGINEERS With the replacements of the variables y,y′,···,y(n) in 1.1 by the functions ϕ(x),ϕ′(x),···,ϕ(n)(x), the EQ. (1.1) becomes an identity over x ∈ (I). In other words, the right hand side of Eq. (1.1) becomes to zero for all x ∈ (I). For example, one can verify that y = e2x is a ...
