Align left side of fraction in math

[Marcelo Laia]

Hi,

I'm trying to vertical center the left side of bellow math equation:

f  = { v } over { { h } times { %pi } times { { DAP^2 } over { 4 } } }

I do a lot of google search and found solutions only for LaTeX.

I try to use stack and phantom, but I isn't have a solution.

Have you a time to point me out a solution?

Thank you so much!

What do you try to improve? The part 'f=' is correctly at the same
vertical position as the main fraction bar.

Kind regards
Regina

Greetings,
Not sure I understood exactly what you want, but this is the best I can
come up with (2 possible options):

f  = { alignl { phantom { h } ` v phantom { %pi } } } over { { h }
times { %pi } times { { DAP^2 } over { 4 } } }
newline
f = matrix { v # phantom { a } # phantom { a } } over { matrix { h
times %pi } times matrix { { DAP^2 } over 4 } }

I hope this helps.
Rémy.
