# Question: New to this forum need help with Maple for general equations

Regards, I am conducting independent research in my university and I was recomended to use this software but since I am more familiar with matlab it feels harder to use maple and I'm making many mistakes.

My question is how to solve the following equation w(xi) = a_0 + a_1 * xi + a_2 * xi^2 + a_3 * xi^3 + a_4 * xi^4

So I defined xi = x/L

and gave some boundary/initial conditions for this equation(don't know if this is right)

w(0) = 0 : w(L) = 0 : w''(0)=0 : w''(L)=0

Now I would like the program to solve the coefficients I proposed in my initial equation. a_0,a_1,a_2 etc.

It seems that maple is not remembering the boundary conditions im giving or i am not using the correct command to solve for the coefficients. I have tried assigning the values for w(0) := 0 and w''(0):=0 but it does not work for the second one. What am I doing wrong?
