題目是
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.
一開始我的想法是a>0 a=0 or a<0
三種情況 =0的話 看起來是個變數可分離的ODE
若非0 則 非齊次 非正合 也很難變成一階線性...
然後就卡住了 所以上來求解= =|
先謝謝解題的各位了
題目是91年台大土木
