Hello, I am trying to display certain fractions in numbers, I am typing up a notecard that I will be allowed to use on my AP Calculus final. The notecard must be 3 in. x 5 in. or smaller. Due to terrible handwriting and fading pencil(We have been adding to it since the beginning of the class) I figured typing it would leave me with a readable and durable copy.

I need to display fractions, such as 1/2, like this:

1

-

2

but, of course, not so large. I want the numbers to be directly over top, not angled like this: ½

What would be the best way to do this? I have tried Grapher, but the image is to small to size properly(I have over 25 equations to fit on the card, front only).

I also need to display roots, integrals, summations, and if possible limits properly. Is there an application that I can use to do this, that I could copy paste from or something like that?

Thank you!

I sugget continuing with Grapher but when printing select the pdf button in the print dialog (bottom-right corner), then select "Open PDF in Preview".

now you can use the rectangular selection tool in Preview (select the menu item "Tools > Rectangluar Selection", to select then copy items to Numbers where you can place and scale as needed.

twenty years ago we did this by writting it nice and large on a peice of paper, then using this thing called a copier to scale it down to size nicely. Today, You could esaily scan in a full size version, then drop it into a program like numbers or keynote and scale it to the right size.

Hello BlueReaper46,

Did you try this :

Launch  Grapher.app in Apple Applications Utilities :

2D window

equation editor (above the graph place)

select and copy in the equation editor

paste into a TextEdit or Pages etc. page with your text.

Grapher How to for equation editor in "Instruction for Use - Grapher" pages 49-54 on website

http://y.barois.free.fr/grapher/

Also you may use MathType (full or lite), very convenient for Pages.app

Here is an example showing a nice size for a math expression :

Hi,

I understand (may be I’m wrong) you want to type 25 mathematical expressions, that is 25 lines (?), on a very small card 3“x5“, i.e. 76.2x127 mm in current international units.

That means 127/25 = 5.08 mm i.e. 2/10 inch height for each formula.

Of course this can be done on a special size of paper 3“x5“ printing (menu File > Page Setup… to enter a customised paper format - beware of printer margins) for a Word or Pages window :

— launch Grapher.app from Applications Utilities ;

— type the first equation in the Grapher Equation Editor field ;

— select and copy it ;

— paste it into the Pages or Word page 3“x5“ window ;

— Pages.app allows you to place this equation anywhere you want and to change its size as you like (bigger or smaller), I presume that Microsoft Word can do the same ;

— same process for each equation…

May I ask these questions : how to use such a card ? Is it not better to learn your math course ? Did you write your own list of formulae on a small notebook in order to read it every two or three days, at least once a week ? I’m 76 now and my notebooks for mathematics, mechanics, probability, physics, etc. are still readable after 57 years or 44 for the youngest one, and I’m not a math teacher !

So long,

YB24

The reason for this card is it is a few "given" equations, equations that we will see numerous times, such as the summation approximation for sine, cosine, e^x, or the integral for certain equations. Those equations are only given because we are not required to memorize them, but what to do with them. Such as giving the summation approximation for e^(x^2), if you want a simple example of the use. Another purpose of this card is what you said, memorizing. As we use the card over and over we start to memorize the equations on it, just from using them so often.

It cuts down on how much we need to memorize for our final exam, but trust me, not by much.

I want to type it for 2 reasons:

1. I have horrible handwriting.

2. I want to share the typed version with my teacher so he can share it with future classes if he wants to.

Hi !

I built a small table 3“x5“ this way :

— launch Pages.app (and not Numbers) ;

— choose a usual page size (for me it was A4  210x297 mm (8.3“x11.7“)

— Menu Insert >Table with 2 columns 3.81 cm (1.5“), and 13 rows 0.97 cm (0.385“), no headers, no footer, uncheck Automaticaly resize to fit content (Inspector Table) ;

— select the whole table, Inspector Text : Center Text, Align to the middle, Spacing Line 1, others 0.

When you’ll print this work with the printer set to 100 % you’ll get a 3“x5“ table on the A4 sheet of paper.

Next job is to fill up the table with formilae :

— launch Grapher.app (Applications Utilities), 2D window ;

— enter ONE formula in the Equation Editor (above the graph place) ;

— select and copy it ;

— paste it into the Pages window, but Out of the table ;

— Inspector Wrap : check Floating, uncheck Object causes wrap ;

— select the formula in Pages, ajust its size to fit a place in the table (maximum 1.5“ long and 0.385“ high) ;

— drag it to its right place on the table.

That’s it for one equation.

Repeat the process 26 times… I tried an example using 19 equations in 20 cells of the table (I had to merge two cells for a long formula).

I must say all equations are readable even for my old eyes !
