How to study the behavior of a vector valued function?

In summary, a vector valued function is a mathematical function that maps inputs and outputs as vectors. To graph, the input vector is plotted as the x-axis and the output vector as the y-axis. The domain is the set of possible inputs, while the range is the set of possible outputs. The derivative is a vector of derivatives, found using vector calculus rules. These functions have real-world applications in physics, engineering, economics, and computer graphics.

Hi, I would like to know how to treat a vector valued function when I want to know where are minima, maxima and saddle points.

Thanks in advance!

Perhaps there is some way to consider such properties, but to me, such concepts no longer have meaning. How could you say a vector has a minimum or maximum value in a region or neighborhood? You could consider the magnitude, but that's a scalar function and requires no more thought than scalar function theory that you're already familiar with.
 

FAQ: How to study the behavior of a vector valued function?

What is a vector valued function?

A vector valued function is a mathematical function that maps a set of inputs to a set of outputs, where both the inputs and outputs are vectors. It can be represented as f(x) = , where x is the input vector and f(x) is the output vector.

How do you graph a vector valued function?

To graph a vector valued function, you can plot points on a coordinate plane using the input vector as the x-axis and the output vector as the y-axis. The resulting plot will show the direction and magnitude of the function at each input point.

What is the domain and range of a vector valued function?

The domain of a vector valued function is the set of all possible input vectors, while the range is the set of all possible output vectors. In other words, the domain is the set of all values that can be plugged into the function, and the range is the set of all values that the function can produce.

How do you find the derivative of a vector valued function?

The derivative of a vector valued function is a vector of derivatives, where each component is the derivative of the corresponding component of the original function. To find the derivative, you can use the rules of vector calculus, such as the product rule or chain rule.

What are some real-world applications of vector valued functions?

Vector valued functions have many practical applications, including in physics, engineering, economics, and computer graphics. For example, they can be used to model the motion of objects in space, analyze the forces acting on a system, or create 3D animations and simulations.
