Thanks for the debugging tip; that's tricky! Unfortunately the term can't be factored out because one term is the sum over 2 and the other is the difference over 2. Still, I reproduced what you said, and then started messing with that 1 (the 1+sign(blah)). If that number is anything other than...
I saved it as a Mathcad 13 file.http://files.engineering.com/getfile.aspx?folder=291ba38e-becc-414b-a931-5c8478734ae1&file=m13_unitless_differential_equation.xmcd
Sorry, I think I was unclear. My issue is with the differential equation to the right of the graphs. The one with 'y' as the variable. I have looked at these two comments and also the comments of a friend of mine. It seems that Mathcad15 cannot handle units in the differential equation. I've...
Okay, now I have a new problem. With the actual problem I'm trying to solve, there are terms that involve velocity in my equation. y2=y0' for example. y2 is a velocity, but Mathcad is treating that term as if it has units of length. Thoughts?
I'm trying to solve a system of 2nd order ODEs that have a similar form to the following situation. Two masses are connected by a spring with spring constant f. m1 is the connected to a spring with spring constant h that is connected to a wall. I'm trying to numerically solve for position as a...
