We should find the directional derivative of the function f ( x, y, z) = x y + y z + z x at the point P ( 1, − 1, 3) in the direction of the point Q ( 2, 4, 5) The partial derivatives are f x ( x, y, z) = y + z, f.

. **The directional derivative** of f(x, **y**, **z**) = 4 e 2x – **y** + **z** at **point** (1, 1, -1) in **the direction** towards the **point** (-3, 5, 6) is ______.

Transcribed image text: **Find** **the directional** **derivative** of the function at the given **point** **in the direction** **of the vector** v. **fx**, **y**, **z**)2y + **y**^**z**, (2, 7,9), v - (2, -1, 2) 1695 134 D(2, 7, 9)- Need Help?

variable u, which is the unknown in the equation. The de ning property of an ODE is that **derivatives** of the unknown function u0= du dx enter the equation. Thus, an equation that relates the independent variable x, the dependent variable uand **derivatives** of uis called an ordinary di erential equation..

The procedure to use the **derivative** calculator is as follows: Step 1: Enter the function in the respective input field and choose the order of **derivative** . Step 2: Now click the button "**Calculate**" to get the **derivative** . Step 3: The **derivative** of the given function will be displayed in the new window..
