수능에서는 상미분방정식이 실제로 나온다.

하지만 더러운 교육과정은 ODE 푸는 법을 실제로 알려주지 않고 심지어 선형대수학도 알려주지 않은 상태에서 미분방정식을 풀게 한다.

그러니 우리는 선형방정식계을 풀어야 한다.

그러면

1a + 2b + 1c + 6d + 2e = 3

3a + 3b + 5c + 3d + 4e = 0

6a + 6b + 7c + 8d + 2e = 9

1a + 1b + 8c + 2d + 4e = 7

8a + 0b + 1c + 7d + 2e = 1

 

일때, a+b+c+d+e 를 구하자.

이 문제 어떠셨나요?

글쎄요
