Greetings, I am trying to implement backward euler implicit method by Newton-raphson iteration. The differential equation is for a simple planar pendulum. So the function for the pendulum is : (1) angularAcceleration (angle) = ( -gravity/length ) * sin(angle); and the update function for...

Thanks, but that's for forward euler? I'm asking about backward euler.

Hi all, I am trying to implement the backward euler integration (in c++) for the pendulum problem. I have the forward euler implemented, but frankly I don't know where to even start from for the implicit integration. I understand the update expressions for implicit, and of course the...
