Re: [微積] 跪求幫解題
※ 引述《hmichellesa (mim)》之銘言：
: 1.show that the differential equation has a regular singular point about z=0
z^2y"+zy'+(z^2-v^2)y=0
: 謝謝各位大大幫忙X-(
z^2 = 0 => z = 0
(z-0)z
------- = 1
z^2
(z-0)^2 (z^2 - v^2)
------------------- = z^2 - v^2 當在z=0處 nonsingular
z^2
所以z = 0是 regular singular point
