Please follow the following model to add your formulas:
Create a page with a descriptive name and type your formula on this page using latex. Then write{{:name of the page with your formula}}
in the place where you want your formula to appear in this table. (Look at the syntax of the geometric series below for an example.) This will allow other people to refer to your formula later on (by refering to the corresponding page) while still being able to view all formulas on this page.
