I apologize if this has been posted earlier (or if this is the wrong section), but I need help with Mathcad.
Having started college as an EE major last year, and restarting next year as a math major next year, math is obviously important for me to use. Mathcad is my preferred math software due to the simplicity of the program, and because it's not a programming language. I'm a horrible programmer, and I would go to great lengths to avoid programming. Originally, I thought that Mathcad couldn't solve differential equations, but after looking through the help files, I found Odesolve and other functions. The thing is, I can't see what the function is. The only "solution" I get is a graph, which won't be accepted as a proper answer to any problem here.
So how do I get Mathcad to return a function when solving ODE's ?
PS: I'm using Mathcad 14, but will upgrade if it's the only way to make this work.
Good tutorial for you here.
You have solved for a function, you just don't realize it. (Need more practice with Mathcad!)
If you want the function that is the solution, that's another matter.
I think following link will also be useful ("Inside Mathcad Series: Programming, Solving, and ODE Solvers"):
For this sort of ODE you can use Mathcad's symbolic Laplace transform functions to help get an analytical solution - see attached.
I haven't really used the UnitsOf() so I messed around a little with your example.
"Help" suggests you change to SIUnitsOf(), but does not seem to matter.
You can refer to the units of a variable to make the function independent of the units used, it's also more concise.
Also, you don't need to use in a graph.
Thanks for the example
