When I put this in my latex source file

\begin{center}
\caption{The plot of the independence copula}
\includegraphics[scale=0.51]{IC.eps}
\end{center}
\begin{figure}


it changes the font of the whole change and it looks ugly.

How can I make this stop?

Thank you!

Hi. Somehow I cannot produce these fractions properly.

$$f(x)=\displaystyle\frac{2}{\pi}\arctan\Big(\frac{t}{a}\Big)\hspace{4mm}\text{if}\hspace{3mm}x=0,1,\ldots$$

Cheers

For the following piecewise function


f(x)= \left\{ \begin{array}{lr} 1 - e^{-(c\lambda)x}& \text{if }X\text{ is exponential} \\1-(1-p_{X})^{cx} &\text{if }X\text{ is geometric}. \end{array} \right

I am trying to align "if X is exponential" and "if X is geometric".

Cheers.
