It’s Carnival Time!

by

Clown in the Carnival The 30th Carnival of Mathematics is up, featuring many intersting posts and some interesting facts about the number 30 (including that 30 is the first Giuga number)!   This Carnival is hosted by The Number Warrior, a blog by Jason Dyer (who teaches high school mathematics).  The Number Warrior also has a recent post I liked that uses triangles on the unit circle to prove 1+csc2θ=cot2θ directly (instead of the way I usually prove it, by starting with sin2θ+cos2θ=1 and dividing through by sin2θ).

Head on over and enjoy the fun!
