In the History list, tap the name of the relation, and then tap Done to show the relation in the entry line.

3.

Use the up and down arrow keys to scroll through the defined relations.

Viewing the History of other Relation Types

In the Graphing view, tap Tools , go to Graph Entry/Edit, and tap the relation type. For example, tap Polar to show an entry line for the next available Polar relation.
