Math & Science ⇒ Too long Denominator in a Fraction

[ahmadyusuf]

Hi guys, i am very happy to find this community since i got problem to share.

I have a fraction with long denominator exceeds the page. Can you help me solve my problem? here is the code:

Code: Select all

\begin{equation}
\dfrac{p_{t}}{p_{i}}=
\dfrac{2j\left(\gamma+\displaystyle\frac{z_{m}}{Z}\right)\sin\:kd\cos\:\phi}{\left(\cos\:kd\cos\:\phi+j\left(1+\dfrac{z_{p_{1}}\cos\:\phi}{z_{f}}\right)\sin\:kd\cos\:\phi\right)\left(\gamma e^{jkd}+z_{m}\left[\cos\:kd+j\left(1+\dfrac{Z}{z_{f}}\right)\sin\:kd\right]\right)-\left(\gamma+\displaystyle\frac{z_{m}}{Z}\right)}
\end{equation}

thank you. ^^

Hi,

the expression is long, and you made it even bigger by using \displaystyle. If you don't want to reduce the size, such as by reducing the font size, you could write it in a different math style. For example, write it as a product with (denominator1)^{-1}*(denominator2)^{-1} with a line break before the multiplication sign.
