标题[理工] [工数]-ODE
时间Mon Sep 14 12:42:25 2009
题目是
solve
dy/dx=(ax+y-2)/(3y-2)
for y(x) with "a" being a real number.
Note that different values of "a" may lead to different solutions
,so that your solutions must include ALL possibilites.
一开始我的想法是a>0 a=0 or a<0
三种情况 =0的话 看起来是个变数可分离的ODE
若非0 则 非齐次 非正合 也很难变成一阶线性...
然後就卡住了 所以上来求解= =|
先谢谢解题的各位了
题目是91年台大土木
