Hi to everybody I'm a new user of Maple How can I solve this system? > eq1:=1039.44*Diff(Diff(ck(r),r),r)+80960*Diff(ck(r),r)*Diff(p(r),r)+80960*ck(r)*Diff(Diff(p(r),r),r)=0; / 2 \ | d | / d \ / d \ eq1 := 1039.44 |---- ck(r)| + 80960 |--- ck(r)| |--- p(r)| | 2 | \ dr / \ dr / \ dr / / 2 \ | d | + 80960 ck(r) |---- p(r)| = 0 | 2 | \ dr / > eq2:=Diff(Diff(p(r),r),r)+(-9.476*10^(-12))*(2*ck(r)+(-7.29*10^(-9)))=0; / 2 \ | d | -11 -20 eq2 := |---- p(r)| - 1.895200000 10 ck(r) + 6.908004000 10 = 0 | 2 | \ dr / > eq3:=Posm(r)=2477.57*(ck(r)-1); eq3 := Posm(r) = 2477.57 ck(r) - 2477.57 > eq4:=u(r)=Posm(r)*r*(9.26*10^(-5)); eq4 := u(r) = 0.00009260000000 Posm(r) r > sol:=Diff(u(r),r); d sol := --- u(r) I've attached the maple worksheet. Please help me soon... Bye bye dr
