@RithwinSK 10 месяцев назад

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 2 года назад

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.
