Answer:
- a) (fx, fy, fz) = (54, 9, 12)
- b) (fx, fy, fz) = (16, 30, 9)
Step-by-step explanation:
a) The partial derivatives of f(x, y, z) = x³yz² are ...
- fx = 3x²yz²
- fy = x³z²
- fz = 2x³yz
At the given point, these are ...
- fx(1, 2, 3) = 3(1²)(2)(3²) = 54
- fy(1, 2, 3) = (1³)(3²) = 9
- fz(1, 2, 3) = 2(1³)(2)(3) = 12

b) The partial derivatives of f(x, y, z) = x² -2xy +3xyz² are ...
- fx = 2x -2y +3yz²
- fy = -2x +3xz²
- fz = 3xy
At the given point, these are ...
- fx(3, 1, -2) = 2(3) -2(1) +3(1)(-2)² = 16
- fy(3, 1, -2) = -2(3) +3(3)(-2)² = 30
- fz(3, 1, -2) = 3(3)(1) = 9
The answer is quarters.
<span>The word which is used to describe the equal
share of the shape is quarters as the shape is equally distributed into four
parts. We can divide shape equally into many parts. If the shape is distributed
into two parts we describe it as halves, if distributed into three parts then
it is said to be thirds.</span>
