Calculator Errors: When Close Isn’t Close Enough (Index)

I’m using the Twelve Days of Christmas (and perhaps a few extra days besides) to do something that I should have done a long time ago: collect past series of posts into a single, easy-to-reference post. The following posts formed my series on how I remind students about Taylor series. I often use this series in a class like Differential Equations, when Taylor series are needed but my class has simply forgotten about what a Taylor series is and why it’s important.

Part 1: Propagation of small numerical errors.

Part 2: A tragedy during the 1991 Gulf War that was a direct result of calculator rounding.
