在给定的初始条件下解微分方程。
1.dydx = 3x2 + 6x + 3, y(0) = −5
2.dydx = 3x2 + 4x − 5, y(0) = 6
3.dydx = −3x2 + 8x + 5, y(0) = 5
4.dydx = 6x2 − 6x + 9, y(0) = −2
5.dydx = 6x2 − 6x + 7, y(0) = −4
6.dydx = 6x2 + 4x − 5, y(0) = −5
7.dydx = −6x2 − 8x − 8, y(0) = −8
8.dydx = −6x2 + 8x + 4, y(0) = 3
9.dydx = −3x2 + 6x − 2, y(0) = −5
10.dydx = −3x2 − 8x + 3, y(0) = 2
11.dydx = −3x2 + 6x + 3, y(0) = 8
12.dydx = 3x2 + 8x − 8, y(0) = 7
