And place them in the formula. x, y and z will be the numbers that appear in the question, and the points
x0,y0,z0
will be the closest values to x, y and z respectively, which are easy for calculations.
In our exercise, we will define
x=1.002,y=2.003,z=3.004
because these values appear in the question. And we set
x0=1,y0=2,z0=3
because they are the closest values to x, y, and z respectively that are easy for calculations.
After we have defined x, y and z, it is easy to find the function. Just put x instead of the number we set to be x, put y instead of the number we set to be y and put z instead of the number we set to be z. In this way, we get the function
f(x,y,z)=xy2z3
In the formula above we see the function partial derivatives. Hence, we calculate them.
