comment Easy way to add another parameter to Manipulate
Then suddenly I decide I want to add a slider for k I am also little confused in how to help. Why can't you just add a slider for k in the same way you did for the tt? Without explaining more the user functionality you are trying to achieve, this would be the obvious way to do it. Also, making everything in just one Manipulate will simplify things. Manipulate only runs in the UI, so making it work as a function to be called indirectly is a little strange to me.

comment Easy way to add another parameter to Manipulate
why put Manipulate inside DynamicModule? Manipulate is already a DynamicModule? can you not just do everything using Manipulate directly?

comment Use of MuPad code into mathematica
Mupad code is pretty much Maple code for the most part. I use Maple differential equations code as is inside Mupad notebook all the time. See this for some information on Maple/Mathematica code conversions. how-can-i-transfer-mathematical-expressions-between-mathematica-and-maple If you have specific mupad code which does not run in Maple as is, then only choice I know about is manual conversion.

comment Scoping all symbols
Welcome to the world of dynamic interactive languages programming. One replaces the flexibility of coding by more emphasis on the programmer to use their eyes much more to catch errors. In strongly static compiled languages, the compiler can catch many errors or issue warnings, but then one loses the flexibility of quick interactions and the dynamic nature of programming. The problems you describe are not new to Mathematica. Any interactive language will have such problems (Maple, Matlab, Julia, Python, Ruby, Perl, etc...)

comment How do I “evaluate in place” programmatically? Need to evaluate Defer[] result in non-interactive setting
I wish Mathematica documentation for Defer would mention such method. Nothing there that mentions how to evaluate Defer expressions other than evaluate in place method.

@ilian and jens thanks! Yes, this did the trick. I spend long time searching and never saw this trick. Please feel free to post this as answer if you like.

comment Partial derivatives of an implicit equation
They are not the same. Since in your method, you set Dt[y,x] to zero as you assumed that y is not function of x. There is no corresponding action done when one just solves for z and then take derivative of the result w.r.t x. That is why the expression I got was much more complicated. I assume your method is what one should do, as the result you obtain is much simpler ;)

comment Partial derivatives of an implicit equation
I like your solution. I do not understand now why I do not get the same answer as your solution. So I assume I am doing something wrong by solving for z and then taking derivative. So will delete my answer since I need to check why it is different.
