## @C_R sir...i just want to find buck...

@C_R sir...i just want to find buckling load of thin composite square plate under shear loading..do u have any code or idea about this..i understand theory...but to apply in maple...i have a problem ..like this is eigen value problem for example problem in this photo ...i don't know how to apply in maple..i have all value of D and R..so i want to find S...but i dont' know how to start..A(mn) also depend on m and n...(eg m,n = form 1..10) ...can u please advise me?

## @tomleslie sir..i want to integrate...

@tomleslie sir..i want to integrate..this eqations for all values in X and Y.....like for X(1) and Y(1) we got 1 answer...for X(1),Y(2) and...like that....X and Y have each 100 values/ how can i get it..please help me sir

@Carl Love  i dont' get it...sir...if my (m,n,i,j) values are sereis.....like (1..10)...how can i get...M[i,j]....can u please..write code for this...i honestly just didn't see by myself

## @Carl Love hello sir. actually my e...

@Carl Love hello sir.
actually my equations is like that and ..it eigen value buckling problem .....how to get M value ...i dont' know how to ask question...i want M(ij) value...for ..like (i,j,m,n= 1 to 10)...can u help me this..?..o

## hi my (m,n,i,j) values...are all...from ...

hi my (m,n,i,j) values...are all...from 1 to 20....;please...help me guys

## @acer yes those depend on i...here ...

@acer yes those depend on i...here is..my new file..with i=1....but what if...i= 1 t0 20 with odd number.
w depend on i and..t_pe depend on w..so...for example ..if i used.. i = 1,3,5,7....we gonna have..4 w values depend on w and...4 t_pe equations..depend on  w...form t_pe equations (as shown in my file..i want c(i))....like...if i =1...i gonna get w(1) and t_pe(1) ..from t_pe1...i cant c(1)...as shown in figure..but..if i used  = 1,3,5,7.....how can i get..c(i) value.....

my questions will be messsed..please..look at my file...
thak u so much sir..u put too much time for me

## @acer i gonna put another file....i...

@acer i gonna put another file....in this file i used only one value...(so it's clear)...here is my  file .

..Pi.mw...

.in this file i only use i= 1.....so it's easily...but in my real calculation...(i value)  may be like (1,3.5.to ..anyvalue..all will be odd number..)..so ...if i use...(i form 1 to...20...) how to get...derivative..each respective .to each......

(it is Ritz solution to plate bending) ..by the way);
thak u very much..sir...

## @acer how to take derivative of ......

how to take derivative of ...two list....like i want to derivative of....soltion(1) with respect to appro_function(1) and 2 with 2 and 3 with 3...here is my mfile..sir

i think i'm assign wrong...here is my new one..i want to do partial derivative of...solution(1) by appro_function(1) ..and 2 for 2..and 3 or 3 like that

@mmcdara  sir....why it can't get lately..it actually solved...if i go assumptions..i dont' know i can go futher calculations...can u tell me why my style of sovling doesn't worked.

Here is the worksheet.

i want to put table all the value of w

hello Sir,
i think my plot should be ellipse..but it show like this and it show like this..please check
with respect
