Differential equations notations confusionGiven these differential equations: d 2 x d t 2 = 2 Ω d y d t sin ( λ ) − g L x d 2 y d t 2 = − 2 Ω d x d t sin ( λ ) − g L yNow making the following substitutions: d x d t = u and d y d t = v we have the following differential equations d u d t = 2 Ω v sin ( λ ) − g L x d v d t = − 2 Ω u sin ( λ ) − g L yNow here is where I get confused, note that we can write d u d t = f ( t , u ) and likewise for the other equation. But if that is so, then what would be my unknown variable for the first equation? Or is it wrong to write d u d t = f ( t , u )?
