In Classic, this input:
yields this output:
But in Standard, the same input yields
How do I set my options in Standard so that the output format is like it is in Classic?
I poked around "display options" etc. but did not find anything.
I hope someone can help me.
I want to solve numerically the diffusion equation,
diff(csh(rh, t), t) = Dif*(diff(rh^2*(diff(csh(rh, t), rh)), rh))/(r0*rh^2)
where "Dif" is the diffusivity and "r0" is the initial value of rh (the equations were normalized).
subject to the following boundary and initial conditions:
I am struggling again trying to solve very similar pde in Maple V.
Could anybody try running it in the older version? Are there any solutions?

Hi, I'd like to know where's maple directory by default on my computer. I just found a program that would really help which is run on maple. I will join the read me file of the program i want to install.
The unclear part for me is " (b) Copy the file dot.mapleinit in the Bethe root directory into your
home directory where it is read in from MAPLE cp dot.mapleinit ---> [user-home]/.mapleinit"

Anyone know a slick way to change the arguments of a function to possibly different things depending on what they are?
Let's say I have objects a, b and c. a and b are of type function and c is of type set. F is another function object.
F(a,b,c) is defined.
What I want to do is construct F(g(a),g(b), h(c)).....
While solving a différential equation, I encounter an integral:
I have a particular system of partial differential equations to which I want to apply a change of variables involving square roots using PDEtools[dchange]. The result turns out to be not in a simple form due to the square roots. Why is this so ? Is there a better way solving the problem than the one I am suggesting below ?
The system of partial differential equations of interest is the following:
In particular because the TAB key doesn't work in Maple, is it possible to define a shortcut key for a few spaces?
I found this quite annoying that I couldn't simply tab over a few spaces when programming. Is Maple going to fix it in the future? Why doesn't TAB work anyway, did they forget about it?
I have some troubles in solving a system of three trigonometric equations using the function 'solve' of Matleb.The program finds three solutions but a message of 'Warning: Warning, solutions may have been lost' also appears. Does it mean that there are other three solutions? If yes, how can I see also these three numbers?
So, Maple is quite helpful in that it will automatically make certain simplifications for me. But what if I don't want it to. For example, if I enter 2*(2+x), how do I get it to not just simply return 4+2*x?
Consider this to by end goal:
evalb(2*(2+x) = 4+2*x) => false
