Hello friends! I think I have problem rendering this fraction in latex: i over 2. How do I do it? Please note that by writing i, I do not mean number one. I strictly mean lower case letter i. Last edited by Chikis; April 9th, 2016 at 05:06 AM.

$\displaystyle \frac{i}{2}$?

Okay try and write this let see if it will work: 2 bracket open root 3 over 2 plus i over 2 bracket closed. Let see how the symbols will show in latex.

Perhaps this looks just little better: $\displaystyle 2\left(\frac{\sqrt{3}}{2}+ \frac{i}{2}\right)$ where I have used "\left(" and "\right)" to size the parentheses to the fractions.
