Answer:
Hi,
The best option in the list is <u>stop posting her e-mail address on newsgroups.</u>
Explanation:
Unwanted e-mail is categorized as a spam email.These emails can not be entirely avoided because we use the Internet thus it is recommended that you filter them.A program called my email client can help to filter spam though in some cases, it might not be effective.
The techniques Nadia can employ in this case is to hidden her email address when visiting newsgroups.News groups are forums online where people discuss certain topic.Avoid publishing the email in these web sites can hide her tackle this problem. Additionally, Nadia could train the filter serach feature in her email box through repoting such emails using the report button present, avoid responding/openning spam or use a third party program to track spam emails and block them.
Wish you Luck!
In archaeology, mesolithic is culture between paleolithic and neolithic. The term "Epipaleolithic" is often used for areas outside northern Europe, but was also the preferred synonym used by French archaeologists until the 1960s.
Natural systems are systems that came into being by natural processes. Like the rain cycle.
Technological systems are those to whom people intervened or designed. Like diverting water for a rider for land irrigation.
Answer:An initial condition is an extra bit of information about a differential equation that tells you the value of the function at a particular point. Differential equations with initial conditions are commonly called initial value problems.
The video above uses the example
{
d
y
d
x
=
cos
(
x
)
y
(
0
)
=
−
1
to illustrate a simple initial value problem. Solving the differential equation without the initial condition gives you
y
=
sin
(
x
)
+
C
.
Once you get the general solution, you can use the initial value to find a particular solution which satisfies the problem. In this case, plugging in
0
for
x
and
−
1
for
y
gives us
−
1
=
C
, meaning that the particular solution must be
y
=
sin
(
x
)
−
1
.
So the general way to solve initial value problems is: - First, find the general solution while ignoring the initial condition. - Then, use the initial condition to plug in values and find a particular solution.
Two additional things to keep in mind: First, the initial value doesn't necessarily have to just be
y
-values. Higher-order equations might have an initial value for both
y
and
y
′
, for example.
Second, an initial value problem doesn't always have a unique solution. It's possible for an initial value problem to have multiple solutions, or even no solution at all.
