Здравствуйте! Прошу помощи в следующем вопросе:Даны функция z=f(x;y), точка А(x0;y0) и вектор а (x1;y1). Найти:
1. grad z в точке А
2. производную в точке А по направлению вектора а
z=arcsin x2/y; А (1;2) а (5;-12)
1. grad z в точке А
2. производную в точке А по направлению вектора а
z=arcsin x2/y; А (1;2) а (5;-12)

Здравствуйте, olja_12111983!
Вычислим частные производные заданной функции:
Вычислим значения частных производных в точке
Значит,
Вычислим направляющие косинусы вектора
Вычислим производную заданной функции в точке
по направлению вектора
Расчёты нужно проверить во избежание ошибок.
