Comment on How do I transfer Domain from old site to new site? by David M

to delete your existing site you can use a FTP program I use filezilla (a free program) enter your ftp log in details into filezilla then log in to your site with filezilla and right click in the panel with your files in you will have a chose of options one is to delete this will remove your existing site,

then you just upload your new website using filezilla

you will not have to do anything with the domain as it’s still pointing to the same place

if you want to change it just right click and chose download you can then edit them and re-upload

It depends on how you are making the site. Are you using Dreamweaver of another FTP? If you are, you can go to the domain pointing manager and change that. I would also take the old domain and redirect it to the new one. Every hosting site is just a little bit different, so you might want to call them and they will help you out.

Comment on How do I fully restore a domain controller from an MS back up file? by JeffB

You must first break your RAID configuration and restore to a single drive.

I’m not confident you can restore the entire server from Windows Backup.

Once you restore then you can create your RAID again.

I highly recommend a backup program such as Symantec System Recovery whicn makes an image of the server and can be completely restored.

You would just run the BKF file, like you said you’ve reinstalled the files and just run the BKF file, when running "Backup" through system tools, you choose "Restore", your BKF file will have the exact configuration of the domain controller just as long you took an image of the computer and backed up the system state and settings. Why use the windows base back up tool though? you can get better ones, you can get ones that take complete images of your computer and if it goes down you can immediately restore in like 5 to 30mins depending on the size of the image.

Good luck

Comment on How do I find the domain of trig functions? by mom w

If your arcfunction is positive, the angle is quad I.
If your arc function is negative, the quadrant changes, but you would like quadrants next to each other.
so, with that in mind

If arcsin is positive, use quad I
If arcsin is negative, use quad IV.
That makes the domain of arcsin [-pi/2, pi/2]

If arc cos is positive, use quad I
if arc cos is negative use quad II.
That makes the domain [0,pi]

tan is tricky, tan is negative in quad II and quad IV. However, tan 90 is undefined, (hence you will have an open endpoint) and choose quad IV.
If tan is positive use quad I
if tan is negative use quad IV

that makes the domain (-pi/2, pi/2) open endpoints

arcsin is the inverse of sin. So, the domain of arcsin is the range of sin (examine their graphs for a visual insight).

Download Graph 4.3 from http://www.padowan.dk for free.

On "Insert function" type sin(x), then "OK"

On "Insert function" type cos(x), then "OK"

On "Insert function" type tan(x), then "OK"

Choose different color for each function!

Comment on What is the difference between domain and range? Describe a realsituation that could be modeled by a function? by mandynicole_03

Well, let’s say you’ve bought some fence, and you’re trying to make a fenced in field for some sheep (or whatever) to graze in, and of course, you want it to be as big as possible. So, you set up an algebra equation given say X ft of fence and you want to find the biggest area A. Well, without going too much into the algebra, you will get a quadratic equation (an equation with x^2 in it….after all, area is ft^2), and for a quadratic function, you know from algebra that something of the form

ax^2 +bx+c has domain and range of ALL REAL NUMBERS, but here…that obviously doesn’t make sense. You will get a quadratic equation that will give you an answer for putting in negative numbers, but….does a negative dimension of a fence make any sense? Not really. Also, the RANGE is all real numbers too, including negative numbers, but…does negative area make any sense? Certainly not.

So, if the real-life situation was removed, Domain and Range would both be ALL real numbers, but because this equation has a real-life meaning, the domain must be x>0 (a dimension can’t be zero or negative) and the range must be y>0 (area can’t be 0 unless a dimension is 0, which we know isn’t possibles).

So, hope that helps it make more sense.

We say Y is the range because on a cartesian xy graph, Y is generally what we are solving for. The range will be the range of what Y will be on the graph. X is the domain because that tells us what values of X we can use. ie, in some cases the domain will be anything that will not produce an "error" such as a zero in the denominator.

Say I wanted to buy 2 apples a day for 7 days. And I didn’t eat any, how many would I have after 7 days?
So:
day1 = 2
day2 = 4
day3 = 6
day4 = 8
day5 = 10
day6 = 12
day7 = 14

This can be modeled by y = 2x
Y will the the answer, which is the amount of apples I will have after X number of days. So looking at my answers (from above), the range will be 2 to 14. The domain will be 1 to 7, because I am only looking at it for 7 days. Technically, in the equation y=2x, the domain can be any real number and the equation will still work. But since I specified for only 7 days, the domain is 1 to 7.

Suppose that y = sin(sqrt(x))

The domain is x >= 0, because you can’t take the square root of a negative.
The range is -1 <= y <= 1, because the sine of any number can’t be more than 1 or less than -1
