Trying to solve an ODE (nonlinear, first-order)

Hello,

I just started using MATHCAD prime 3.0 without any experience with previous versions of MATHCAD. My first task is to solve an ODE (nonlinear, first-order: as analyzed by mathematica):

(dV(x)/dx)^2 - (dV(x)/dx|x=0)^2 = A*(exp(B*V(x))-1), with only two boundary conditions V(0) = 0 and V(d) = -Vd

For the details, please see the file attached below.

I guess the problem occurs because of the (dV(x)/dx|x=0)^2 term in the left-hand side of the ODE. But I do not have a clue how to fix this problem.

I tried to be as clear as possible.

Thank you very much,

Sungyeop
