Is it just me or is the math here incorrect?

specifically, I don't see where the last step G(h_t) = etc. follows from
Yup, that's a mistake. Shouldn't have the +h term at the end.
Stared at this for a while also. Yes this is wrong.
Thank you for bringing this up. Legit, was bothering me to the extent I didn’t believe I could comprehend the article.
So what is the correct equation? Or has the article already been fixed?
the mistake is simply that G(h(t)) = F(h(t))/dt, rather than G(h(t)) = F(h(t))/dt + h(t), i.e. it's only in the text following the inset equations. you can verify this by looking at the "Evaluating ODEs" section.

edit: looks to have been fixed now.

Thanks a lot. reading
