Hello, not sure how to begin solving this as I have only come across differential equations with dy/dx and not the second derivative. Any advice would be appreciated, especially worked solutions. Thanks!
Are you sure this is covered in your course, this is further maths only in edexcel. If you still need help with it that then look at this
Thanks for that Mshabana. I haven't seen this in the single maths A level textbook but it appeared in one of the mixed exercise sections, but wasn't labelled as an extension or anything. Wanted to make sure I knew how to do it anyway
This is how I solved this. The -or- part is where I reached a dead end, ignore that. But splitter2017’s post I think is wrong. Second derivative of e^λχ is not λ^2 x e^λχ, but how I wrote it. I think.

The 2nd derivative of e^(λx) is definitely (λ^2)e^(λx) check it on Symbolab if you disagree. λ is NOT a function it is a constant. You do NOT use product rule.

You’re right. My bad. Completely forgot that λ was a constant 😅
