Typesetting inline math?

Questions
1

HI … I am trying to type the following inline math:

Express the polynomial,
ctrl( p = 2 + 3[Alpha]^1 - [Alpha]^2 + [Alpha]^3 ctrl),
in terms of the Falling Power Basis,
ctrl( F = (1, [Alpha]^UnderBar[1], [Alpha]^UnderBar[2], [Alpha]^UnderBar[3]) ctrl),
and the Rising Power Basis,
ctrl( R = (1, [Alpha]^OverBar[1], [Alpha]^OverBar[2], [Alpha]^OverBar[3]) ctrl} of ctrl( P^3 ctrl).

I must be doing something wrong because the inline math does not typeset as math, except that the [Alpha} does show up as the greek symbol alpha.

Any suggestions as to how I can correct the inline math attempt above or any documentation you could point me too.

Thanks.

Are you typing into an “inline cell”? It is done with the menu command Insert > Typesetting > Start inline cell. If you know TeX it corresponds to ... (math mode). See the workflow page on “insert inline math in text”

Sorry, you already typed into an inline cell. What is the problem then? The powers?

4

Yes the powers.

Are you aware of the technique shown in the “enter math notation” workflow?

Thanks again for the pointer link … I think my problem is to have the exponent to have an UnderBar or OverBar.

It works fine in math mode … for example:

fallingpwr = {1,\[Alpha]^UnderBar[1], \[Alpha]^UnderBar[2],\[Alpha]^UnderBar[3]}

Thanks for all your help, I will experiment and eventually I will get it. :slight_smile:

You can use a palette, for example the basic math assistance. Select the “1” and press the underbar icon in the palette. The underbar has a keyboard shortcut too.

Thanks again … I will try to install the basic math assistance palette.
