Happy Tau Day

Happy Tau Day
6/28 is τ Day.
Tau = τ = one turn around the circle = $\frac{C}{r}$ = 2π = 6.28318…
How do mathematicians celebrate τ Day?
Protest! Share anti-π propaganda.
And eat two pies…

Raised-cosine filter
The raised-cosine filter is a filter frequently used for pulse-shaping in digital modulation due to its ability to minimise intersymbol interference (ISI). Its name stems from the fact that the

Reflex: Math Fact Fluency
Website Review
Pros: Kids build math fact fluency through engaging games that hold their attention.
Cons: The program lacks extensions to build on math fact fluency.
Bottom Line: Reflex is a clever tool to build kids' fluency in all four math operations.

Ces\`aro summability
Cesàro summability
Cesàro summability is a generalized convergence criterion for infinite series. We say that a series $\sum_{{n=0}}^{\infty}a_{n}$ is Cesàro summable if the Cesàro means of the partial sums converge to
some limit $L$. To be more precise, letting
