Calculus Derivates

Hi everyone, 

I'm trying to solve a sistem of two coupled differential equations on Mathcad Prime using Odesolve, but I'm not getting sucess. Anyonde can help me? (I guess that the error is on the term highlighted in second equation)

Its hard to debug just a picture - always attach your worksheet, too, (and state which version of Prime it was created with).

Werner, I'm using the MathCad Prime 5. The worksheet is been sending

The error message is not really helpful.

 

When you look for "odesolve", the help states

"The ODEs must be linear in their highest derivative term"

which is not the case in your example (ya'^2), but I am absolutely not sure if this really is the cause for the solve blocks failing. Actually I doubt that thats the problem as the error message does not change if I delete the square operator in ya'.
