i'm not sure if this is the right place but I'm trying to get my head around derive 6 and i have a couple of questions that don't seem to be coming out right...
d[tex]^{2}[/tex]y/dx[tex]^{2}[/tex] + 8dy/dx + 16y = (4e[tex]^{-4x}[/tex])(sinx+cosx)[tex]^{2}[/tex] ; y(0)=y'(0)=0
so i inputed DSOLVE2_BV(8, 16, (4·^(- 4·x))·(SIN(x) + COS(x)) ∧ 2, x, 0, 0)
but its not throwing up the right answer?
