Help: Equation Editor and Actuarial Notation
David Frick
need to create an equation that includes the present and future value of an
annuity.
There is a special notation used to denote an annuity. It looks like the
notation used in long division but flipped horizontally. The present value
of an annuuity would be written as "A angle n at i" where the angle is the
annuity notation covering n, the number of compounding periods.
Word's equation editor comes with an "angle" symbol but it does not allow
you to place a subscripted "n" below it.
Does anyone know how I can create the annuity equations?
Is there a third-party equation editor available? I don't want to spend a
lot of money on this because I only have a few equations to write.
I suppose I could create most of the equation using Word's equation editor
and then copy and paste it into Visio and then draw the "angle" symbol
free-hand.
But does anyone know a better way?
Thanks
Dave

add a subscript?

up from the bottom and place the angle symbol in the big box.

The problem is that the subscripted "n" appears too far below the the angle.
I tried changing the size of the "n" to full but it still is not possitioned
properly.
Is it possible to adjust the position of the subscript?

I used the box from the super|sub/script template, centre, bottom row. I
inserted 'n' as the subscript and the angle in the big box.
However, when I go to Format | spacing, the subscript option has no effect
on the appearance.
I also tried the box from the super|sub/script template, centre, middle row
with the same results.
What is the different between these two options? And why can't I adjust the
spacing of my subscript.
I changed the size of 'n' to full so it would be the same size as 'i'.
Would this have anything to do with the problem?
Thanks

I'm not familiar with that symbol, but if you send me a link to a
document on the web where it's used, I may be able to do a better
job of helping. (Or send me a DOC or PDF file directly -- not to
the newsgroup.)

Did you want it DIRECTLY below the angle symbol, or in the
"subscript" position (i.e., below the baseline of the angle
symbol, but offset to the right)?

MathType is the professional version of Equation Editor, and
works essentially the same way, but has many more features. You

I'll be responding to your other post separately, so please read
both posts for a complete answer.

First I need to make sure I understand which template you're
using. You're using both the one called "Large operator with
under-script limit". At least that's the one that's in the
center of the bottom row in the "Subscript and superscript
templates" palette. (To see the names of the templates that I'm
referring to, point to one of them with your mouse pointer, and
look at the status bar.)

If I understood correctly the template you were using, to adjust
the position of the subscript (more correctly an "underscript"),
you need to adjust the "Limit depth" option under Format |
spacing.

That would be the "Under-script (limit)" template.

The difference is that the former uses an operator size of
"Symbol" (as defined in the Size | Define menu), and the latter
uses an operator size of "Full".

No.

I have two gifs I will send you directly. One shows how the formual looks in
a text book and the other is as close to this as I can get with equation
editor.
Please let me know what you think.
