How can I let the following code look good ?
\begin{align*}
&\text{Als} &&a,b \in H\\
&\Rightarrow &&a,b\in H_1 \land a,b \in H_2 &&\text{Definitie van doorsnede}\\
&\Rightarrow &&ab^{-1}\in H_1 \land ab^{-1}\in H_2 &&\text{Group axioma's}\\
&\Rightarrow &&ab^{-1}\in H &&\text{Definitie van intersectie}\\
&\Rightarrow &&H\leq G &&\text{Ondergroep test}
\end{align*}
No there is just way too much whitespace. Is there a way to control the amount of whitespace ?
Hm.. in codecogs it does look good. So this is how I would want it to look:
Best Answer
the desired result can be produced by
alignat*
-- but then you have to manage the spacing yourself:edit: a look at the
amsmath
documentation would be salutary --texdoc amsldoc
on a tex live system.the (required) argument after
\begin{alignat}
was introduced to make it possible to determine (for ease of macro programming, it appears) the width of a particular single column so that it can be treated in a special manner if necessary. the value is equal to the number of&
s in the line with the most, minus one. an alternate method of calculating the value is given in the user's guide cited above.
