comment FullSimplify on TransformedDistribution
Looks like a bug. I would report it to support@wolfram.com, or I could do that for you.

comment DatePlus changes in V10.2, can I return to previous behaviour?
The best practice is to always use DateValue when working with Dates. This decouples your code from the way that these date functions will choose to represent their output.

comment Plotting multivariable integration
I think NumericQ still really should be used in this case. The function could easily be used in other contexts and it's behavior should be consistent. I've updated the answer.

comment DSolve returns an answer that is not a solution
Put more simply. Do you consider this to be a bug? DSolve[{Sqrt[f'[x]] == -x}, f[x], x] {{f[x] -> x^3/3 + C[1]}}

comment DSolve returns an answer that is not a solution
Looking at the errors, it looks like a branch cut problem. Solvers in general don't handle these kinds of branch cut problems very well. See this example: (wolframalpha.com/input/?i=Sqrt%5Bf%27%5Bx%5D%5D+%3D%3D+-x). This isn't really a bug as much as an expected hardship of computer algebra

revised InverseFunction of [E, 1, 1][c/Sqrt[K[1]]] isn't it just Log[c/Sqrt[K[1]]?

You used E as a function. Mathematica just went with it. Go back to your DSolve expression and use Exp instead of E. Mathematica used E as a function only because you asked it to.

comment I can not open any notebook
What messages do you see when you try to open the file with Mathematica? Walk us through step-by-step. Can you run Mathematica? What happens when you go to File > Open in the menu? What happens when you click the file you want to open? It's important to write up the steps you go through and what happens at each step.

comment Is Mathematica a Turing-complete language?
@Yu-SungChang Not neccessarily. There are restrictions you can place on recursion that will not longer make it turing complete. The Coq programming language is an example of this.

comment Why don't some functions work in trial versions of Mathematica?
The trial version has always had this type of restriction in it. But, this is the first time you can try out this stuff without even needing to install the trial.
