a. The gradient is
b. The gradient at point P(1, 2) is
c. The derivative of at P in the direction of is
It looks like
so that
Then
Answer:
Slope of the line DV = -1
Step-by-step explanation:
Let point D (-5, 1) be
Let point V (-1, -3) be
Plug in the appropriate values,
slope equals -1
Let
. Then
and
are two fundamental, linearly independent solution that satisfy
Note that
, so that
. Adding
doesn't change this, since
.
So if we suppose
then substituting
would give
To make sure everything cancels out, multiply the second degree term by
, so that
Then if
, we get
as desired. So one possible ODE would be
(See "Euler-Cauchy equation" for more info)
