This Desmos graph allows you graphically investigate the relationship between epsilon and delta when considering the formal definition of limit. There are two accompanying videos on the YouTube page: Video 1.2a explains the interpretation of epsilon, delta, and how you can make sense of the formal definition of limit. Video 1.2b shows how to solve…

## Limits from a graph (1.1)

This Desmos link shows what is happening graphically when you construct a table of values to investigate a limit. Desmos is also very useful for quickly evaluating functions at several inputs (just define f(x)=……, and then type f(0.01), f(0.001), etc. in lines below it).
