I'm writing an presentation of the project where I took a "standard" equation and modified it slightly. I would like to therefore show this by replacing the standard equation with its modified version.
I've seen a few solutions here, but they all deal with RHS replacements and don't work with the LHS.
I would like (this is merely as an example)
A &= B
to be replaced by
A + C &= B^D
while maintaining the alignment around the equations. I've tried using
\alt<2->{A + C}{A} &= \alt<2->{B^D}{B}
but while \alt solves RHS replacement (especially if used with \phantom to deal with possible vertical erros), with a variable LHS the result still wobbles. How can this be solved?
A = B. – Wasabi Dec 16 '14 at 00:34
