    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?)

  • I put it in \begin{equation}..\end{equation} block..

  • @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.

As Joseph wrote, just use the following:



  = e^{j(2\pi/T_{0})kt}
