find a power series (centered at the origin) satisfying the following ODE zf''(z)+f'(z)+zf(z)=0 assueme f(0) =1 and simplify the result, using sigma notation hint: f(z)=sigma(n=0->∞)a(n)*z^n=a(0)+a(1)z+a(2)z^2+a(3)z^3+... 求解此題? -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 151.181.36.98 ※ 文章網址: https://www.ptt.cc/bbs/Math/M.1509300963.A.2F2.html
