WebDec 17, 2024 · Equation 2.7.2 provides a formal definition of the directional derivative that can be used in many cases to calculate a directional derivative. Note that since the point (a, b) is chosen randomly from the domain D of the function f, we can use this definition to find the directional derivative as a function of x and y. WebBy the Sum Rule, the derivative of with respect to is . Step 3.2. Differentiate using the Power Rule which states that is where . Step 3.3. Differentiate using the Power Rule which states that is where . Step 4. To write as a fraction with a common denominator, multiply by . Step 5. Combine and .
