Given:
The function
Formula used:
The directional derivative of a function f is given by,
Where,
Calculation:
Consider the function,
Partially differentiate the above function with respect to x,
Now, partially differentiate the function with respect to y,
The direction is
Thus, the directional derivative of a function f is given by,
Substitute the values
Hence, the directional derivative of the function
