Exp & Log functions

Posted · Add Comment

In algebra an inverse function is one that is symmetric around the line y=x. Two functions that are inverses of each other are the exp (exponential) and log (logarithmic) functions. The design below (created for one of our articles on math and visual art) shows how exp becomes log when reflected in the line y=x.
