The Gradient direction and rate of maximum increase

In summary, the gradient direction and rate of maximum increase is a concept that describes the direction and magnitude of the steepest increase in a function. It is calculated by taking the partial derivatives of the function and is important in optimization problems and physics. It can be negative, indicating a decrease in the function, and can be applied in various real-world scenarios such as engineering, economics, and machine learning.

Homework Statement


What is the direction and rate of maximum increase?
f(x,y) = x^2 + y^3, v = <4,3>, P = (1,2)


Homework Equations





The Attempt at a Solution


The direction should be as same as the gradient so < 2,12>
The rate of maximum increase is magnitude of the gradient so sqrt(4+144) = sqrt(148).
Is that right?
