수학동아 4월호 특집기사 'AI 귀 뚫는 삼각함수'에서 삼각함수 개념 설명을 한 부분에 오류가 있어 

내용을 정정합니다.

 

39쪽 '탄젠트함수'에 대한 설명에서 \sin45^{\circ}와 \cos45^{\circ} 가 \frac{1}{2}로 잘못 표기됐습니다.

해당 오류를 \frac{\sqrt{2}}{2}로 수정합니다.

 

혼란을 드려 죄송합니다. 앞으로 더 꼼꼼히 확인하도록 하겠습니다.

    삼각형은 변 꼭짓점이 모두 3게인대 각도기의 직각을 왜 삼각형 이라고 할까? 

    변은 2개 꼭짓점은 1게인대

    (밑에 선만 그리면 삼각형)
