Opened up YouTube, got nerd sniped with a math problem. After a bad morning, it was the perfect thing to take a break working on. Still haven't watched the actual video, just the thumbnail...will do that once I get off of work to see if we got to the answer the same way (well, the proof that is). #math

The problem is: given 3 does not divide "a" and 3 does not divide "b", prove that 9 divides "a^6 - b^6"

For those who think that going out is the wrong thing to do today: Here's a quick puzzle for you.

Construct the Dice

By Hans-Karl Eder

Marie has one regular die labeled with the numbers 1, 2, 3, 4, 5 and 6 and a second cube that is completely blank. She labels this cube in a special way. If you roll both dice, you can get the following totals: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12. The special part: all 12 total vaslues are equally likely to be rolled. How did Marie label the cube?

Last nerd snipe of the week which got me browsing through my YouTube feed:
Find all primes `p` such that `p^2 2` is also prime.

As recently as last year I was recommending to my #Math students that if they were having trouble with an elementary algebra expression, they could try using the Google search bar to solve or simplify something. Maybe I should show them this instead.🀦

google's AI displays multiple algebra errors and arrives at a clearly incorrect solution to a search bar query about solving a polynomial equation.   (apparently my no-punching-down personal rule does not apply in this situation.)

Another nerd snipe for today: solve the definite integral from 0 to pi for the sine of 2x times the cosine of x dx. This one took a minute for me, but got the answer two different ways. Still a nice way to exercise integration techniques and trig identities.

Got nerd sniped again...lol. Not a horrible problem and there's two ways to solve it.

Given "3 sine theta plus 4 cosine theta equals 5", solve for the tangent of theta.
