    How do I make sums full size in cases?

    I.e. in the following, the sums are inline, but I'd like them larger.

    f(z)=\begin{cases}-\frac{1}{z-2}\sum_{n=0}^\infty \left(\frac{z-2}{2}\right)^2, & \text{for}~ |z-2|<2<br /> <br />
\\ \frac{2}{(z-2)^2} \sum_{n=0}^\infty \left(-\frac{2}{z-2}\right)^2, &\text{for}~|z-2|>2<br />
 \end{cases}

    Is it possible?

    If you add \displaystyle to the two cases, you get this:

    f(z)=\begin{cases}\displaystyle-\frac{1}{z-2}\sum_{n=0}^\infty \left(\frac{z-2}{2}\right)^2, & \text{for}~ |z-2|<2<br /> <br />
\\ \displaystyle\frac{2}{(z-2)^2} \sum_{n=0}^\infty \left(-\frac{2}{z-2}\right)^2, &\text{for}~|z-2|>2<br />
\end{cases}
