Hi All,
I'm trying to write some code so that I can solve Euler-Bernoulli Beam Bending problems. These are fourth order differential equations and require boundary conditions. I have two questions about them:
1. How do you use DSolve when the boundary condition is not at 0 (example: y[L]==5 as opposed to y[0]=5)
2. Is this an example of what a final line of code would look like?
DSolve[{y''''[x]==Var1, y'''[0]==Var2,y''[L]==Var3,y'[L]=Var4,y[L]=Var5},y[x],x]

Thank you for any help.
