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 !

       Don’t forget your card and microscope for your exam…

      So long,

    Hi !

      Thanks for your explanations.

      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 !

     

      Good luck for your exam,
