Mathematics For Engineering Students 1908
1908년에 출판된 학생용 교재입니다.
기초적인 내용이 들어 있네요.
전부 보진 않았는데, 초중고에서 배우는 내용이 대부분인 듯 합니다.

Step 2 (FTC의 마법): 면적의 변화율(미분)은 그 지점의 그래프 높이 f(A)와 같습니다. Step 3 (보정): 다음 A = 현재 A - (면적 오차 / 현재 높이) 공식을 사용하여 A를 이동시킵니다. 결론: 오차를 현재 높이로 나누면, 오차를 메우기 위해 필요한 가로 길이(ΔA)가 나옵니다. 이 과정을 반복하면 정답에 도달합니다! const canvas = document.getElementById('graphCanvas'); const ctx = canvas.getContext('2d'); const iterText = document.getElementById('iterText'); // 수학 설정 const targetArea = 20; const f = (x) => Math.sqrt(x) * 2; // 피적분 함수 f(x) = 2√x const F = (x) => (4/3) * Math.pow(x, 1.5); // 정적분 결과 F(x) = ∫ 2√x dx = 4/3 * x^(3/2) let A = 1.5; // 초기값 let iteration = 0; let animating = false; // 그래프 드로잉 설정 const scale = 50; const offsetX = 60; const offsetY = 380; function drawGrid() { ctx.strokeStyle = '#f1f3f4'; ctx.lineWidth = 1; ctx.beginPath(); for(let i=0; i 2026 04.11 참값 : A = ±2√5 근사값 : A≈±4.472135954999579392818347 2026 04.10 fx-570 ES 입력 결과 초기값 입력 반복 수식 입력 반복 결과 2026 04.10 파이썬 코드 검증 결과 초기값: 5.0 반복 1회차: 4.5000000000 반복 2회차: 4.4722222222 반복 3회차: 4.4721359558 반복 4회차: 4.4721359550 반복 5회차: 4.4721359550 초기값: 10.0 반복 1회차: 6.0000000000 반복 2회차: 4.6666666667 반복 3회차: 4.4761904762 반복 4회차: 4.4721377913 반복 5회차: 4.4721359550 2026 04.10 감사합니다. 주말 잘 보내세요. 2026 03.06
