The derivative or derivatives? If it is the derivatives just take the partial derivatives inside the vector
 
  • #3
no it is the derivative
 
  • #4
And it does not say with respect to what?
I would guess taking all the first derivatives
f(x,y,z)=(x^2-2xy+z,y^2+z^2)
f'(x) = (2x-2y,0)
f'(y) = (-2x,2y)
f'(z) = (1,2z)
But I guess the question is to advanced for me:-(

What is calculus in vector spaces?

Calculus in vector spaces is the application of calculus principles and techniques to vector spaces, which are mathematical structures used to represent and study quantities that have both magnitude and direction. This branch of mathematics is also known as vector calculus.

What are some common applications of calculus in vector spaces?

Calculus in vector spaces has many applications in various fields such as physics, engineering, economics, and computer graphics. Some common applications include the study of motion and forces, optimization problems, and the analysis of vector fields and curves.

What are the key concepts in calculus in vector spaces?

The key concepts in calculus in vector spaces include vectors, vector functions, vector derivatives, vector integrals, and vector fields. These concepts are used to describe and analyze quantities with both magnitude and direction in a mathematical framework.

What are the differences between calculus in vector spaces and traditional calculus?

While traditional calculus deals with functions of one or more variables, calculus in vector spaces focuses on functions of vectors. This means that the concepts and techniques used in vector calculus are specifically tailored to the study of quantities with both magnitude and direction.

What are some useful tools for performing calculus in vector spaces?

Some useful tools for performing calculus in vector spaces include vector operations such as addition, subtraction, and scalar multiplication, as well as the dot product, cross product, and gradient. These tools allow for the manipulation and analysis of vectors and vector functions.
