Здравствуйте дорогие эксперты,
Нужна помощь в решений задачи:
186. Дана функция z=f(x;y) и две точки A(x0;y0) и B(x1;y1) требуется:
1) вычислить значение z1 в точке B
2) вычислить приближённое значение z1(вектор) в точке B, исходя из значения z0 функции в точке А и заменив приращение функции при переходе от точки А к точке В дифференциалом
3) Оценить в процентах относительную погрешность, получающююся при замене приращения функции её дифференциалом
4) составить уравнение касательной плоскости к поверхности z=f(x;y) в точке С(x0;y0;z0)
z=x^(2)+y^(2)+2x+y-1 A(2;4) B(1,98;3,91).
