Overview of Directional Derivative Calculator
The directional derivative is a mathematical operation that measures the rate of change of a function in a particular direction. It is a generalization of the ordinary derivative, which measures the rate of change in the direction of the x-axis.
The directional derivative is defined as follows:
$$D_\mathbfuf(\mathbfx) = \lim_h\to 0 \fracf(\mathbfx + h\mathbfu)
f(\mathbfx)h$$
where uis a unit vector in the direction of interest, xis the point at which the derivative is being calculated, and fis the function being differentiated.
