# Big fractions for exponentials

Does anybody know how to represent this style of fraction? Notice that it is located inside an exponential.

• It's just $v_{k}(t) = e^{j(2\pi/T_{0})kt}$ by the looks of it: did you try simply typing in the appropriate math mode material? (I note you asked an earlier very simple math mode question: have you studied a basic beginners guide to LaTeX?) – Joseph Wright Jan 11 '14 at 9:16
• I put it in $$..$$ block$$..$$ – john john Jan 11 '14 at 9:18
• @john john: If you're having trouble with questions like these, you should take a look at Web Equation: write the equation on the screen and it will show you how it's written in LaTeX and what that LaTeX output will be. – DJP Jan 11 '14 at 15:48

\documentclass{article}
$$v_{k}(t) = e^{j(2\pi/T_{0})kt}$$
