개념 기사 기사 작성법
내가 아는 수학개념을 쉽게 설명해주세요!
기사 작성법
좋은 기사 를 쓰려면 어떻게 해야 할까요?매스포터 여러분 안녕하세요!
01
제목 정하기
기사를 볼 때 가장 먼저 보는 게 무엇인가요? 바로 제목입니다. 아무리 잘 쓴 기사라도 제목이 재미없으면 눈길이 안 가기 마련입니다. 기사의 제목은 기사의 주제를 담고 있으면서도 사람들의 흥미를 끌 수 있어야 합니다.
02
육하원칙 지키기
도형의 기본 요소가 점, 선, 면인 것처럼 문장의 기본 요소는 '육하원칙(언제, 누가, 어디서, 무엇을, 어떻게, 왜)'입니다. 육하원칙을 잘 지킨 문장은 명확하고 많은 정보를 담고 있기 때문에 이해하기가 쉽습니다.
03
띄어쓰기와 맞춤법 지키기
기사의 목적은 새로운 정보를 정확하게 전달하는 것입니다. 그런데 기사에 띄어쓰기나 맞춤법이 잘못돼 있으면 신뢰하기 어렵겠죠? 기사를 다 쓰고 잘못 쓴 단어나 문장은 없는지 한 번 더 확인해주세요.
04
문장은 짧게, 다양한 단어 이용하기
한 번에 읽기 편하도록 문장은 짧게 써주세요. 문장이 길어지면 주어와 서술어가 맞지 않거나, 같은 말을 반복하는 등의 실수를 하기 쉬워요. 문장을 줄이고 싶으면 '굉장히', '매우'와 같은 미사여구나 '그런데', '따라서'와 같은 접속사 중 불필요한 표현을 빼주세요.
또 한 문장에서 같은 단어가 되풀이되지 않게 다양한 단어를 이용해보세요. 글이 훨씬 풍성해 질 거예요.
05
사진 또는 그림 설명하기
기사 내용과 관련 있는 사진과 그림에 대한 설명을 꼭 달아주세요! 기사의 내용을 이해하는 데 큰 도움이 된답니다. 이때 본인이 직접 찍은 사진만 사용해 주세요. 포털 사이트에서 허락없이 가져오는 사진이나 그림은 저작권에 문제가 될 수 있습니다. 저작권에 문제가 없는 사진일 경우 꼭 출처를 밝혀주세요!
Plus +
재미있는 퀴즈 내기
매스포터에서는 기사의 마지막에 기사 내용과 관련 있는 퀴즈를 내야 합니다. 퀴즈를 통해 기사를 읽는 사람들이 내용을 한층 더 깊게 이해할 수 있을 거예요!
위의 사항을 제대로 지키지 않은 기사는 홈페이지에 보이지 않을 수 있으니, 꼭 ‘기사작성법’을 숙지하고 기사를 작성해주세요
복소수
앞에서는 복소수의 정의에 대해 알아보았습니다 . 지금부터는 복소수의 성질과 같은 것을 알아보겠습니다 .
복소수의 특징은 우리가 새로운 수의 범위 , 복소수라는 범위만 창조했지 어떤 결과가 성립하는 지는 아직 모른다 .
복소수 (complex number) 의 정의는 임의의 두 실수 a, b 에 대하여 a+bi 꼴로 나타내어 지는 수를 실수에서 확장된 수가 복소수 이므로 실수는 복소수이다 .
또한 복소수 a+bi 에서 b 가 0 이 아닌 수를 허수 (imaginary number) 이라고 하고 , 이 중 a=0 이고 b 가 영이 아닌 허수 , 즉 bi 꼴의 수를 순허수라고 한다 .
전체적인 수 체계 정리 .
글자를 못쓴 것에 대한 점은 정말 죄송하다 .
또 유리수 안에 황색으로 되어있는 것은 양의정수 , 주황색은 음의 정수이다 .
아참 허수 a+bi 에서 a 는 실수부분이고 b 는 허수부분이다 .
두 복소수의 실수부분과 허수부분이 각각 같을 경우에 두 복소수는 서로 같다고 한다 .
복소수가 서로 같을 조건은 다음과 같다 .
a, b, c, d 가 실수이고 , i= 루트 – 1 일 때 ,
1) a+bi = c+di ⇔ a=c 이고 b=d
2) a+bi=0 ⇔ a=0 이고 b=0 일 때
여기서 주의해야할 점이 있는데 , a, b, c, d 에 대한 정보 ( 실수 , 유리수 ) 가 주어지지 않으면 , 이 조건들은 사용할 수 없으므로 주의해야한다 .
복소수가 서로 같을 조건은 굉장히 중요한데 , 복소수의 사칙연산과 연계되기 때문이다 .
이로써 오늘 기사는 끝 ...
다음시간에는 켤레 복소수에 대해 알아 보겠습니당 ^^
퀴즈
1) (a+1)+(b-1)i = 0
다음 조건을 만족시키는 실수 a, b 의 값을 구하여라 .
