Find the derivative of the function at P 0 in the direction of A. f(x,y,z) = 3 e^x cos(yz), P0 (0, 0, 0), A = - i + 2 j + 3k

Alik [6]

The derivative of $f(x,y,z)$ at a point $p_0=(x_0,y_0,z_0)$ in the direction of a vector $\vec a=a_x\,\vec\imath+a_y\,\vec\jmath+a_z\,\vec k$ is

$\nabla f(x_0,y_0,z_0)\cdot\dfrac{\vec a}{\|\vec a\|}$

We have

$f(x,y,z)=3e^x\cos(yz)\implies\nabla f(x,y,z)=3e^x\cos(yz)\,\vec\imath-3ze^x\sin(yz)\,\vec\jmath-3ye^x\sin(yz)\,\vec k$

and

$\vec a=-\vec\imath+2\,\vec\jmath+3\,\vec k\implies\|\vec a\|=\sqrt{(-1)^2+2^2+3^2}=\sqrt{14}$

Then the derivative at $p_0$ in the direction of $\vec a$ is

$3\,\vec\imath\cdot\dfrac{-\vec\imath+2\,\vec\jmath+3\,\vec k}{\sqrt{14}}=-\dfrac3{\sqrt{14}}$

Question 4/11 i’ll mark brainliest

Answer:

The two pieces of information are needed to prove that line AB is a perpendicular bisector of line CD are:

m∠AGD = 90° ⇒ B

CG = GD ⇒ C

Step-by-step explanation:

If line m is the perpendicular bisector of line AB and intersect it at point D

D is the mid-point of AB

The angles around point D are right angles (the measure of each one 90°)

Let us use these facts to solve our question

Look at the given figure

∵ Line AB is the perpendicular bisector of line CD

∵ Line AB intersects line CD at point G

∴ G is the midpoint of CD

→ That means the point G divides the line CD into two equal parts

CG and GD

∴ CG = GD

∵ AB ⊥ CD at G

∴ ∠AGD and ∠AGC are right angles

→ the measure of the right angle is 90°

∴ m∠AGD = m∠AGC = 90°

The two pieces of information are needed to prove that line AB is a perpendicular bisector of line CD are:

m∠AGD = 90° ⇒ B

CG = GD ⇒ C
