계산기를 갖고 놀다 보니 신기한 걸 좀 많이 발견했죠
지금 기록한 노트가 없긴 하지만(나중에 수정해둘게요)
sin,cos으로 시작해서
sin(cos(cos(tan(sin(...(n)))...)) 이 값을 계산기로 구해보면
(sin 뒤에 오는 식은 무작위)
n값에 관계 없이 일정한 값이 나옴을 볼 수 있습니다!(단, tan90 제외)
근데 이것만 있으면 이 글을 안썼겠죠?
이 값을 역수 취해보면
57.xxx(이거도 나중에 추가)
가 나오는데, 이는 tan 89.0000001값과 유사합니다!
왜 그런거지... 되게 신기하지 않나요?
그 이유를 아시는 분은 제게 알려주세요!
사례는...음...
