I hold a very long equation and this causes me some problems. I crave it to lookup the following way:
left side = right side\\
+continuation of right side\\
=right side again modified\\
+continuation of the modified rights side\\
=result
I first used that align environment:
\begin{align*}
\pi^{M}(s^{M},f^{M},x^{M}) :&= 12s^{M}+14f^{M}-(s^{M})^2-(x^{M}-4)^2-(f^{M})^2-x^{M}f^{M}-(x^{M})^2
&=12\times6+14\times\dfrac{48}{7}-6^2-\left(\dfrac{2}{7}-4\right)^2-\left(\dfrac{48}{7}\right)^2
-\dfrac{2}{7}\times\dfrac{48}{7}-\left(\dfrac{2}{7}\right)^2\\
&=69,14
\end{align*}
However, the matter is, that I'm doing this in a presentation and the column width is limited. Despite of that {align} doesn't adjust the expression in of margins of the film (by slow the expression before a + or a - sign and continuing it on the next line), but makes it anfahren out of and whole page reach.
I thought in multline, however, the problem is, that multline aligns the first row left the second to last when one-time rows centered and last row right. This works well, if one has an expression of the sort a+b=c+d+e+f+g+h=j, where there's only first row amongst initial row or consequence. Even, in my case, I have some arithmetic formation (meaning into additional row) furthermore so I need the equal sign of the row: "12\times6+14\times\dfrac{48}{7}-6^2-\left(\dfrac{2}{7}-4\right)^2-\left(\dfrac{48}{7}\right)^2
-\dfrac{2}{7}\times\dfrac{48}{7}-\left(\dfrac{2}{7}\right)^2" to be aligned under the first equal sign. So now I use this version:
\begin{align*}
\pi^{M}(s^{M},f^{M},x^{M}) :=& 12s^{M}+14f^{M}-(s^{M})^2-(x^{M}-4)^2-(f^{M})^2\\
&-x^{M}f^{M}-(x^{M})^2\pause\\
=&12\times6+14\times\dfrac{48}{7}-6^2-\left(\dfrac{2}{7}-4\right)^2-\left(\dfrac{48}{7}\right)^2\\
&-\dfrac{2}{7}\times\dfrac{48}{7}-\left(\dfrac{2}{7}\right)^2\pause\\
=&69,14\pause
\end{align*}
Does anybody have preferable ideas? Thank you
