Solve the following differential equations 1. y" + 5y' + 6y = 108x^2 , y(0) = 18 , y'(0) = 26 2. (x^2)y" + xy' - 4y = (x^2)lnx 3. yy" = 2(y'^2) 4. y" - 4y + 5y = (e^2x)cscx 5. (x - y)dx + (x + y)dy = 0 6. (x^2)y' + y = 2(x^3)(e^1/x) 7. xy' + (x + 1)y = (e^x)(y^2) Apply the iteration method to y' = x + y , y(0) = 0 -- 既然上了賊船...... 那就努力成為海賊王吧! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 118.168.173.117
