For the basic values of theta for sin cos tan (0,30,45,60,90) you can use the trig hand trick Face your palm toward you and label your pinky (0°) and move up with the other basic values. To find sin(30°) count the number of fingers below whatever finger is labelled for 30°(ring), so there is one finger below your ring finger(pinky) For sin: Sqroot of number of fingers below/2 For cos vice versa: Sqroot of number of fingers above/2 For tan flip your hand over so your nails face you(your pinky is still 0 but it’s counting down now): Sqroot of the number of fingers above/number of fingers below 👍

[@paull2937]

Here’s a formula for pythagorean triples. Given n>or=3, any odd length side n, which is the shortest side, take n^2/2, and +/- 0.5 to this number. And you have a pythagorean triple. For example, take the number 13. 13^2/2 = 84.5. The 2 other side lengths are 84.5 +/- 0.5, which is 84 and 85. And there you go. 13, 84 and 85 is a pythagorean triple. No need to memorize anything.
