Can someone please give me formulas and explanations to these

y' and y'' or just y^(n) from xx / xy / yy (i hope that "from" is the right way how to say it, maybe "by")

when i have { x=ch[t], y=(sh^2[t])^1/3 }

Or maybe explayning which one from above is equal to this:

y'' from xt * t' from x

and if y' from x = y' from t / x' from t, is y' from y the same turned around? or that would be x' from y?

basicly i need all kind of formulas for my notes x:
