Recall the definition of a limit: we say if:
For all there exists a such that whenever .
Here we will look at the above function , whose limit at 1 is .
Use the applet above to find how values epsilon and delta relate to each other:
When , provide a value of that satisfies the conclusion of the limit definition:
For the same , also provide a value of that
does not
satisfy the conclusion of the limit definition:
Now make epsilon smaller. When , provide a value of that satisfies the conclusion of the limit definition:
For the same , also provide a value of that
does not
satisfy the conclusion of the limit definition:
