Здравствуйте, Влад Алексеев!
В предыдущем ответе во второй задаче неверно вычислена вторая производная.
Параметрическое представление первой производной
x=(1-t)/t2
yx=-(t+2)/(t-2)
Вторая производная
yx=(yx)t/xt=[(4/(t-2)2)/[(t-2)/[t3]=4t3/(t-2)3

Орловский Дмитрий проверьте пожалуйста ваше решение. У меня есть ответ к примеру и он таков: y''=4t^3/(t-2)^3

Да я согласна. Взяла, вместо первой производной х по t, в знаменатель поставила вторую производную. Мда. Невнимательность. Формулу написала верно, а применила не очень. Посыпаю голову пеплом.
