Calculating gradient vector
The gradient vector is a vector that points in the direction of the greatest rate of increase of a scalar function. It is a vector formed by taking the partial derivatives of the function with respect to each of its variables, and putting them together in a vector.
To calculate the gradient vector of a function f(x,y,z), you can follow these steps:
1. Find the partial derivative of f with respect to x. This is denoted by ∂f/∂x.
2. Find the partial derivative of f with respect to y. This is denoted by ∂f/∂y.
3. Find the partial derivative of f with respect to z. This is denoted by ∂f/∂z.
4. Put the partial derivatives together into a vector. The gradient vector of f is given by the vector (∂f/∂x, ∂f/∂y, ∂f/∂z).
For example, consider the function f(x,y,z) = 2x^2 + 3y^2 + z^2. To calculate its gradient vector, we do the following:
1. ∂f/∂x = 4x
2. ∂f/∂y = 6y
3. ∂f/∂z = 2z
4. The gradient vector of f is (4x, 6y, 2z)
Therefore, at any point (x,y,z) in the domain of f, the gradient vector of f points in the direction of the greatest rate of increase of f at that point.
