what is wrong..in the past ..this equations was solved..now it doesnt' solved anymore...integral equations

hello sir..i'm new..and i want to know how to put command prompt ..between two command line .i read but i didn't find..

hey guys...please watch my file and help me. when i call(Am)...it only shows last value. how can i get all (Am) value in like seq or table

restart

with(LinearAlgebra):

i := [seq(2*i-1, i = 1 .. 10)];

[1, 3, 5, 7, 9, 11, 13, 15, 17, 19]

(1)

for i in i do A[m] := (x/a)^(i+1)*(1-x/a)^2 end do;

x^2*(1-x/a)^2/a^2

 

x^4*(1-x/a)^2/a^4

 

x^6*(1-x/a)^2/a^6

 

x^8*(1-x/a)^2/a^8

 

x^10*(1-x/a)^2/a^10

 

x^12*(1-x/a)^2/a^12

 

x^14*(1-x/a)^2/a^14

 

x^16*(1-x/a)^2/a^16

 

x^18*(1-x/a)^2/a^18

 

x^20*(1-x/a)^2/a^20

i want to solve..this what is happening..i used maple not a long time ago.help me

restart; with(LinearAlgebra)

i := 1;

1

(1)

w := c[i]*(x/a)^(i+1)*(1-x/a)^2*(y/b)^(i+1)*(1-y/b)^2;

c[1]*x^2*(1-x/a)^2*y^2*(1-y/b)^2/(a^2*b^2)

(2)

(1/2)*(int(int([D__11*(diff(w, x, x))^2+2*D__12*(diff(w, x, x))*(diff(w, y, y))+4*D[66]*(diff(w, x, y))^2+D[22]*(diff(w, y, y))^2-2*q*w], x = 0 .. b), y = 0 .. a))

Error, (in int) wrong number (or type) of arguments: for an operator integrand a range without a variable of integration is expected, got x = 0 .. b
