Hey, guys. Can you help me one more time about the non-homogeneous differential equation, the function is shown below:

ODE:

y''(x)-0.00003019*y(x)^0.337=[9.542*10^(-13)]*x  ;    0<=x<=2945

BCs:

y(0)=0; y'(2945)=0; 

Actually, the right part is applied bending moment due to own weight. it is very small, but I don't think I may neglect it.  The exact solution is the best answer for me, the numerical solution is also available for me.  Can you show your code of Maple? Thank you for your any help in advance.   Sincerely, I appreciate it so so so much!!!

Hey, friends, I have a differential equation to confuse me too much!  The question is shown in the below:

ODEs:

y''(x)-0.00003019*y(x)^0.337=0  ,       0<x<2945

BCs:

y(0)=0,    y'(2945)=0.0116 

 

I want to have the numerical solution, I used to plot y(x) and y'(x) , but errors shows me "jacobian is singular at left endpoint, use midpoint method instead."  Thank you for you any help in advance!!!  

Can you give me the code to figure it out in Maple?  Thank you so so so so much!
