I can success to sepeate. I was very surprised because it is very simple. I have a question.
Actually, I also thought your method to seperate.
But I gave up because aa'.r(r1,v,theta)[1 gave [0.07184, -0.07184]
I think ar(r1,v,theta):=aa'.r(r1,v,theta)[1 may be same.
that is, a.r(r1,v,theta)=[0.07184, -0.07184]
So Why are they different? I can't understand well.
It has to do with the way you set up your equations. Mathcad can not find a solution with a=a'. The values Mathcad finds are a valid solution of your equations - if you set a for a' you get a value close bu not exactly to the value you demanded.
And then I have another question.
I got result value.
But I can't understand because your result value is different with my result value.
this is your value
I don't know what I did to get that value. Maybe I used your functions a.r and a'.r or played around with something else.
Anyway, I get the same result as yours now.
See attached for proper handling of degrees.
