Уважаемые эксперты! Пожалуйста, ответьте на вопрос:
Найти grad U(A) и производную Ua(A) в точке A(0.9;0.5;0.7)
по направлению вектора a(4;3;3) функции
U = 4x9 + 4y5 + 3z6 + 2x9y4z7 + 5arcctg(x4y4z3)
Найти grad U(A) и производную Ua(A) в точке A(0.9;0.5;0.7)

Я правильно понимаю, что задана функция U=4x9+4y5+3z6+2x9y4z7+5arcctg(x4y4z3)?

Здравствуйте, mustang289!
Заданную функцию я продифференцировал с использованием онлайн-калькулятора http://math24.biz/partial_derivative. Значения частных производных в точке
я вычислил с использованием MS Excel (прикреплённый файл).
-- градиент заданной функции в точке A.
-- направляющие косинусы вектора 
координаты единичного вектора 
направления.
-- производная заданной функции по направлению вектора 
в точке
