Math & Science ⇒ My formula is too long

[quasar987]

Hi,

I am working on slides and when I enter the following code,

Code: Select all

\begin{displaymath}
f(x)=
\begin{cases} 
n & \text{if } x \in \mathbb{Q} \ \text{and } x=m/n \ \text{where } n>0 \ \text{and } gcd(m,n)=1 \\
0 & \text{otherwise}
\end{cases}
\end{displaymath}

the forumla is too long for the width of the slide. What I would like to do is write the condition "if x \in [...] gcd(m,n)=1" on two lines nicely.

How would I do something like that?

Thanks!

You can try something like the following.

Code: Select all

\begin{displaymath}
  f(x)=
  \begin{cases}
    n & \text{if } x \in \mathbb{Q} \ \text{and } x=m/n \ \text{where } \\
    & n>0 \ \text{and } gcd(m,n)=1 \\
    0 & \text{otherwise}
  \end{cases}
\end{displaymath}

Where to exactly set the line break is up to you.


Best regards
