Hi everyone:

I'm going to write code to give me the following matrix A?

 

 

hi everyone:

how can I solve this below equation?

w:=(x)->sin(lambda*x)+b*cos(lambda*x)-sinh(lambda*x)-b*cosh(lambda*x);

b := -(sin(lambda*L)+sinh*lambda*L)/(cos(lambda*L)+cosh*lambda*L);

L:=10;

equation:=int(w(x)^2,x=0..L)=1;

lambda=????

tnx..

Hi everybody?
