Understanding Directional Derivatives
The directional derivative of a function measures the rate at which the function changes at a point in a specified direction. Learning how to calculate directional derivatives is a fundamental concept in multivariable calculus and has numerous applications in science, engineering, economics, and more.
Definition
The directional derivative of a function \( f(x, y) \) at a point \( (x_0, y_0) \) in the direction of a unit vector \( \mathbf{u} \) is defined as:
\[ D_{\mathbf{u}}f(x_0, y_0) = \nabla f(x_0, y_0) \cdot \mathbf{u} \]where \( \nabla f \) is the gradient vector of \( f \) at \( (x_0, y_0) \), and \( \cdot \) denotes the dot product.
How to Use the Directional Derivative Calculator
- Enter the multivariable function \( f(x, y) \) you want to calculate the directional derivative for.
- Specify the variables (e.g., \( x \), \( y \)).
- Enter the point \( (x_0, y_0) \) at which you want to calculate the directional derivative, using commas to separate the coordinates.
- Enter the direction vector components, using commas to separate the components.
- Direction Vector: A direction vector \( \mathbf{v} = (v_x, v_y) \) indicates the direction in which you want to measure the rate of change of the function at the given point. The directional derivative measures how the function changes as you move from the point in the direction of this vector.
