Math vertical alignment problems

[swingkyd]

I'm trying to get the following formula to align vertically properly:

Code: Select all

D_f  = sqrt{1+{left({T_a over t_f}right){left ( 1-e^{{-2t_f}over T_a} right )} }}

One could get the impression that the following fraction:

Code: Select all

left({T_a over t_f}right)

is the base raised to the power of:

Code: Select all

{left ( 1-e^{{-2t_f}over T_a} right )}

when in fact it is just a multiplication. and I don't want to add an operation in there since "dot" and "times" are vector operations and not multiplication.
Any ideas how to get them to align correctly?

It still isn't right, but something like this will at least make the bracket size match a little better:

• ­
  D_f  = sqrt{ 1 + 
               left({T_a over t_f}right)
               left(
                 stack {
                   1-e^{{-2t_f}over T_a} #
                   phantom x
                 }
               right)
  	   }

thanks...whereas I agree it's not perfect...it is certainly better. This is a nifty trick! Do you suppose this is an issue worth starting?

Can't hurt to bring it up...

It gets still better if you leave out the first set of parentheses.

.. which parentheses?

You have left({T_a over t_f}right)
Try T_a over t_f
