Hi, Finally, after reading source code of math-ali.mkiv, I found the best way to typeset my multiline equation as follows
\starttext \placeformula
\startformula
\startalign[n=3]
This means that you must have three "columns" in each line
\NC x^2 + y^2 \NC = z^2 \NC \NR[eq:1]
\NC\NC = w^2 \NC + u^2\NC \text{(by \in{Equation}[eq:2])} \cr
This has 4 columns. You do not get an error message because you use \cr instead of \NR. That also messes up the alignment of the next equation.
but I don't know what is going on here. Exactly, eq:2 and eq:3 has the same output but they can not be interchanged. Can someone explain this code?
This is how I would do this. \placeformula \startformula \startalign[n=3] \NC x^2 + y^2 \NC = z^2 \NC \NR[eq:1] \NC \NC = w^2 + u^2 \NC \text{(by \in{Equation}[eq:2])} \NR \NC \NC \quad + v^2 + r^2 \NC \NR[eq:2] \NC \NC \quad + v^2 + r^2 \NC \NR[eq:3] \NC \NC = v^2 + r^2 \NC \NR[eq:4] \stopalign \stopformula Aditya
