Tālāk atvasini, kā daļu pēc t un tad izdali ar atvasinājumu no x pēc t kas arī būs otrās kārtas atvasinājums pēc x

dy pret dx esi vietām sajaucis! Rezultāts pareizs, ja apmaina skaitītāju un saucēju vietām.
Tālāk tad kā akels rakstīja.

Emmm, tas nozīmē to pēdējo (t^3/kvadrātsakne(1-t^2)) kas man tur ir dabūtais, vienkārši vēlreiz jāatvasina tā kā iepriekš?
