오늘은 sin과 cos는 학교에서 배운 실험을 다시하려고 한다.
실험 내용은 물이 얼면 얼음이 되었을때 부피는 얼마나 증가할까를 하고 있었다.
sin이 물 110ml를 종이컵에 넣었다.
그 다음 sin이 냉동고에 넣는다.
얼음이 된후 cos가 부피를 구한다.
그런데 물을 냉동고에 넣은지 1시간후에 tan가 와서 그 물을 x ml마셨다.
그 사실을 모르는 sin과 cos는 그 물이 얼음이 된후 cos는 부피를 구하는데 110 ml로 부피가 그대로여서 이상하게 생각했다.
나중에 tan가 물을 마신 것을 알게된 후 tan에게 말을 하러 간다.
sin:tan 너 물 몇 ml 마셨어?
tan:내가 그걸 어떻게 알아 물 마실때 ml같은거 재면서 마시니?
cos:하긴 그렇게 마실리가 없지.. 그런데 잘못한건 너잖아.
tan:몰라 나 그냥 갈께
sin,cos:어딜 가려고!!!
tan:으악 튀어
sin:tan가 튀었단 말이지 그렇다면 난 tan가 오면 혼내줘야 되겠네.
cos: 그런데 우리가 한 실험은 어떻개 할거야?
sin: 그냥 tan가 마신 물 양을 구하는 수 밖에 없지...
cos:그냥 그렇게 하자.
문제는 말그대로 tan가 마신 물의 양은 얼마나 될까?(풀이 필수)
