Re: Solving symbolically a system of equations

hello everyone, I'm new at mathcad and Im using the prime 3 version. Reading this and looking for in internet I haven´t been able to find how to solve system of equations with end value condition.

What I'm trying to do is to solve g ' ' (x):=M with M:=P2*x-P3 for g ' (x=0) := 0,   g ' (x=L) := 0, g (x=0) := 1, and   g (x=L) := 0.

I already tried with solve block and with replace like doing it step by step almost by hand but, is there an eassier way?

I paste a sheet with averything i have tried

thanks.
