我在 Maple 中用微分方程和一些初始条件做一个快速的问题,但我收到一条错误消息,鉴于上下文,我似乎无法理解。谁能快速详细说明这里发生了什么?我该如何解决这个问题?
> KVLl2 := -4*(i2(t)-2)-12*(i2(t)-i3(t)) = 0;
-16 i2(t) + 8 + 12 i3(t) = 0
> KVLl3 := -12*(i3(t)-i2(t))-4*i3(t)-3.5*(diff(i3(t), t)) = 0;
/ d \
-16 i3(t) + 12 i2(t) - 3.5 |--- i3(t)| = 0
\ dt /
> mySoln := dsolve({KVLl2, KVLl3, i2(0) = 1, i3(0) = 1}, i2, i3);
Error, (in dsolve) found the following equations not depending
on the unknowns of the input system: {1 = 1}
