Уважаемые эксперты! Пожалуйста, ответьте на вопрос:
Требуется :
1)Вычислить А приближённо с помощью дифференциала функций двух переменных.
2)Записать функцию z=f(x,y);координаты точек A(x0,y0)и B(x1,y1).
3)Составить уравнение касательной плоскости к поверхности z=f(x,y) в точке C(x0,y0,z0),где z0=f(x0,y0)
4)составить уравнение нормали к поверхности z=f(x,y)в точке C(x0,y0,z0).
A=0,982 + [$8730$]1,04.
z=x2 + [$8730$]y, x1=0.98, x0=1, y1=1.04, y0=1

Здравствуйте, katyushka.zaharova.91!
2. Запишем сначала, меняя порядок выполнения задания, функцию, например,
и координаты точек
1. Вычислим число
3. Составим уравнение касательной плоскости к поверхности
в точке 
- уравнение поверхности;
- уравнение касательной плоскости к поверхности 
в точке 
- искомое уравнение касательной плоскости.
4. Составим уравнение нормали к поверхности в точке
- канонические уравнения нормали к поверхности в точке
- искомые (канонические) уравнения нормали.
