Testing Equations







I hope this equation appears OK. I created it with Microsoft Word Equation editor and then had to use a screen capture to put it into a jpeg file for uploading. It seems too small and fuzzy in Preview mode. The jpeg looked fine.

Catherine here --

Steve, I went into the html window and put in random numbers for width and height...which isn't getting rid of blurriness, obviously, but is making the image larger.

I frequently have this problem, and often I can make images larger by making the measurement figures larger -- usually without horribly distorting the image.

Flickr works pretty well, btw. The nouvel Obs cover is a flickr image from a scan of the cover.

OK, I really would like to figure this out. any comments?

Catherine Johnson said...

Obviously, I have ZERO expertise (though I am going to make a run at getting recent comments back up).

I can read it.

Oh!

I do have a possible fix.

If you look at the html window, you can ....

wait...let me see if I can do it

I use Wikipedia's Tex ability:

Do you want it with or without the parentheses?

Also, upload it to blogger to get rid of the ugly url. I basically just wrote a TeX formula while editing the sandbox, hit preview and took the url of the resulting image.

This is what I used to create it:

\sum_{i=1}^{12} (Teacher's\ opinion)_i \neq Curriculum

Place it between "math" tags (e.g. [math][/math] but replace [] with <> -- blogger won't accept my tags!)

Right click, copy link location...

12 teacher opinions does not a curriculum make. Haha.

Was this for your town's policy or is this making a remark on the actions of some national board?

le radical galoisien said...

*do not.

The hazard of changing one's sentence halfway.

Catherine Johnson said...

Of course, I have no idea how to read the notation.

Sigh.

I did teach myself logarithms this week.

Teaching yourself logarithms isn't easy.

At least, not for me.

Here:

Typeset using:

\sum_{i=\mbox{K}}^{12} \mbox{Teacher's Opinion}_i \not= \mbox{Curriculm}

What I find odd is that if you click on the image, you get a view which is more like what's in the JPEG file.

SteveH said...

It translates to The summation of all teachers' opinions from K (Kindergarten) to grade 12 do not make up a curriculum. It's in response to threads lately about what individual teachers want for "their" kids. Apparently, their own opinions take precedence over what the shcool (or AP course) requires.

SteveH said...

Thanks lrg. I need to give Tex a try.

le radical galoisien said...

I didn't fix the whole i=1 thing. Oops. (This is what happens when you copy and paste...)

le radical galoisien said...

Here's a fixed version.

I love Wikipedia's Tex rendering feature, especially since you can use the images for your own purposes outside articles.

TeXShop for the Mac comes bundled with LaTeXiT, which makes awesome pdf equations.

I don't know that this affects anyone here at the moment but just for completeness, don't forget that images or pictures of equations are not accessible to persons with visual impairments.

If you uses MathML to create equations in a web page, then the free MathType plugin for Internet Explorer can be used to zoom in on the equations and also to convert them to spoken form. FireFox can display MathML without a plugin and there is a plugin called FireVox that speaks MathML.

(BTW, several different organizations are working on software to convert MathML to braille math.)

The latest version of MathType for Word allows you the option of entering LaTeX (if you know it) and exporting to MathML.

Probably none of this works in blogspot, of course.

If you actually need to know more about this issue and don't feel like using Google, you can probably figure out how to contact me.

That's why I do prefer Wikipedia's rendering feature over PDF cuz it's so convenient. Just click preview, copy link location and paste in your blog post!
