Leibniz QCCQ

Quote:

"In 1673 he made one of his most remarkable discoveries, the infinite series expansion

pi/4 = 1 - 1/3 + 1/5 - 1/7 + 1/9 - ..."

Comment:

When I was reading through the text, this really caught my eye because this was a series that I recognized and always thought was very cool and useful for various circle-involving problems.

Connection:

Just before reading this text, I was doing simple calculations with this series and thought it was very cool that it didn't converge to the most commonly used approximation of pi (3.14) after many steps into the series. Like a rubiks cube, everything works out after the last step. I thought it was cool to find this in the text after just working with it.

Question:

I wonder if we will be using this in the future, since the text mentioned that it had to do with calculus?
