      Best take right here. Trig shows up a lot when you actually do stuff. Woodworking, programming, physics, art, music, philosophy. Math shit is universal human language.

      1209 is 3 times 13 times 31, and cats are better at typing than they are at math.

      In base 10, the sum of the digits of any number that is divisible by 3 is also divisible by 3, so 1+2+0+9=12, implies 1209 is divisible by 3.

      Likewise, 1001 is divisible by 13, so if you split a number in base 10 every 3 digits, and subtract/add alternating sets of numbers, if the result is divisible by 13, the original number is, too. 209-1 is 208, which is obviously divisible by 13, so 1209 is, too.

      Divisibility by 31 in base 10 is harder to check, but 999998 is divisible by 31, as is 999999999999999, so you can just split the number every 15 digits, and add those together, and if the sum is divisible by 31… I’m talking about math to a cat.

    This guy.

    He’s known for a different meme, but he’s used in this one and manages to look like he’s posing at gunpoint after being told “look casual and not afraid. Now, smile.”

      Fair enough, but did they use it? I always felt like focusing on statistics instead of random trig stuff for non stem people people would be more useful

        You need trigonometry in many trades though.

        Meanwhile school level statistics will not help you understand statistics you see better, as you need much more to evaluate the methods used to derive a certain stat.
