Sometimes people including me say it "goes on and on" which sounds like it is growing somehow. But infinity does not do anything, it just is.

### Are All Infinities the Same "Size"?

It is actually simpler than things which do have an end. Because when something has an end, we have to define where that end is. When there is one end it is called a Ray, and when there are two ends it is called a Line Segment, but they need extra information to define where the ends are. But written as a decimal number the digit 3 repeats forever we say "0. So, when we see a number like "0. You cannot say "but what happens if it ends in an 8? This is why 0.

A Googol is already bigger than the number of elementary particles in the known Universe, but then there is the Googolplex. It is 1 followed by Googol zeros. I can't even write down the number, because there is not enough matter in the known universe to form all the zeros:.

For example, a Googolplex can be written as this power tower: That is ten to the power of 10 to the power of ,. But imagine an even bigger number like which is a Googolplexian. But none of these numbers are even close to infinity.

Because they are finite, and infinity is We can sometimes use infinity like it is a number, but infinity does not behave like a real number. Which is mathematical shorthand for " negative infinity is less than any real number, and infinity is greater than any real number". No, because we really don't know how big infinity is, so we can't say that two infinities are the same. In this fifth part--part five of five--we cover a calculus for sequences, numerical methods, series and convergence tests, power and Taylor series, and conclude the course with a final exam. Learners in this course can earn a certificate in the series by signing up for Coursera's verified certificate program and passing the series' final exam.

## Strange but True: Infinity Comes in Different Sizes

Feeling really great after finishing the course. Learnt a lot and gained deeper insights into the calculus. Challenging but worth it! I did have to use supplemental tools to aid in my learning but that may not be the case for everyone.

In "ordinary" calculus, we have seen the importance and challenge! The determination of convergence for such will occupy our attention for this module. I hope you haven't forgotten your big-O notation you are going to need it!
