→ doom8199:題目是不是有漏打 y 對 x 的 ode? 04/02 11:58
→ doom8199:會做那種假設，大概是型如 y' = y^2/x + p(x)y + q(x) 04/02 11:59
→ doom8199:經過變換後可得到 u 對 x 的二階線性 ode 04/02 12:01
→ doom8199:然後在設法找出兩個齊性解; 我猜題目應該是這個意思 04/02 12:01
各位強者們我不懂這題的意思,一直解不出來
Under the variable transformation y=-xu'/u x>0
can you derive the corresponding second order differential for u(x)
what's the particular solution u1(x) of the quation you derived,
and please use the reduction of order method to find another particular
solution u2(x)
