Hi
I am trying to sort a spreadsheet (Sheet 2) which is linked to another worksheet but when I do, the information on sheet 1 gets misaligned. How do I sort it without messing up the informaiton? I tried the absolute references
Expand the sort to include all data fields. Then everything gets sorted 'together'.
I signed up for pre cal for school this fall because i was suposed to take a geometry class this summer. I didnt get into the geometry class, and was wondering how much geometry i actually needed to know for pre cal. Do you think i should take it anyway, or change into a geometry class?
You need geometry to get a good grasp on trig, and you need trig for pre-cal (some places combine trig and pre-cal). I hated geometry, but loved trig and had no problems in pre-cal. So, you just need a general understanding. As to memorizing theorums (or whatever they are called) and all that garbage…..nah.
What are some examples of errors students might have when rounding decimals to the nearest tenth?
rounding the wrong way e.g. 4.75 to 4.7 or they could look to far down the number e.g. 2.3445 rounded to 2.4 when it should be 2.3
Jasper is the last addition and Edward is the first. Which one is Alice?
Here's the timeline from the Lexicon
http://www.twilightlexiconblog.com/?page_id=9
The year they join the family
Edward- 1918
Esme- 1921
Rosalie- 1933
Emmett - 1935
Jasper and Alice (together) - 1950
Although Jasper and Alice were changed in 1863 and 1920 respectively, they were the last to join
I came across this technique when dividing complex/imaginary numbers. When you use the technique on those numbers, it actually simplifies them. I tried using the technique on regular fractions and noticed that it does not change the original fraction. I'm going to assume it doesn't change the value of the complex fractions either, but somehow "re-phrases" them.
You are NOT multiplying the "fraction by its conjugate". You are multiplying BOTH the top and the bottom of the fraction by the same complex number. That is equivalent to multiplying the fraction by 1, which does not change its value.
For example, if you want to simplify (3+2i) / (4+3i) you would multiply both top and bottom by (4-3i). This is the same as multiplying the fraction by (4-3i) / (4-3i) = 1.
The reason this simplifies the fraction is that when you multiply a complex number by its conjugate the imaginary parts cancel out leaving you with a real number. So, you end up with a real number on the bottom of the fraction, which you can distribute to the two parts of the top.

How do i convert fractions to percentages using a scientific calculator as well?
This annoyed me for ages ! I finally figured out how to do it on mine but all scientific calculators are different. Mine is a Casio. Once you have typed in the sum and pressed equals you then press the button that looks vaguely like this: S>>D. This will then convert it to whatever it didn't give you. So if it gave you the answer as a fraction it would turn it to a decimal and vice versa.
The button is inbetween the right closed bracket ) and a button: M+. Or just above the delete (del) button.
Hope this had helped and you buy some chance have the same calculator as me 
Hello…we just recently moved and due to the lack of good schools I will be homeschooling my 13 year old daughter. Now before I took her out of school she was in advanced classes. I know there are websites were she can do the lessons online but I don't want her on the computer so I need printable worksheets that are either free or considerably cheap.
There are different sites for different subjects, but in general:

The identity property entails: 0 + A = A
The identity property of multiplication entails: 0 * A = 0
Adding 0 to a term results in the same term. Multiplying zero by a term results in 0.
Are there any practical applications to this property? In other words, in what instance would you use this property? I realize that you would use it simply when you add or multiply by zero. But, are there any other algebraic applications?
Thanks.
The practical application is when you have a dozen cans of beer and each one is empty, you know that you have no beer left because
12 x 0 = 0
You must use all 5's. Nothing except division, multiplication, subtraction and addition. Good luck!
and yes, it is possible!
actually this is possible
(5*5*5-5)/5
(25*5-5)/5
(125-5)/5
120/5

I am halfway through my college level algebra course and i wanted to know what im getting into because i have pre-calc next semester. So, what is pre-calc generally about? How does is differ from algebra?
in precalc. you do lots of trigonometry, analytical geometry,matrices,probability,vectors, Elementary functions( polynomial functions, rational functions,exponential and logarithmic functions)
It is harder than algebra I and algebra II, but easier than linear algebra. Precalculus uses many techniques in algebra, so make sure you have a good foundation in algebra!
