What type of simplification do you imagine is possible using the integer assumptions?

I already used continuation to overcome an "Initial Newton iteration not converging" error. Continuation does not help with the general "Newton iteration not converging." In a few hours I'll post the worksheet for the BVP.

You asked the same question on Oct 22, 2014. I tried solving it with Maple then, and it failed with "Newton iteration is not converging."

To solve the problem, you need to assume that the ground makes a right angle with the wall and that the ground stays level for the 9 feet out to the base of the ladder. It's not a very realistic assumption because the ground usually slopes away from a wall for drainage, but I know that a right angle is what the problem's author intended.

switches:= proc(sq::list(identical(0,1)))
local switches:= 0, k;
     for k to numelems(sq)-1 do
          if sq[k] <> sq[k+1]then
               switches:= switches+1
          end if
     end do;
     switches
end proc:

L:= combinat:-permute([1$2, 0$2]);

switches(L[4]);

switches ~ (L);

Also, you made explicit the implied multiplication "3 y" in the definition of f.

Your partial derivative symbol is being treated as a variable in its own right rather than as an operator. I don't know why. But you can get around this problem by explicitly typing diff rather than relying on menus and palettes. For example, diff(W(x,y), x, x).

It's utterly obvious if you read showstat(Matrix)! But I'll humor you anyway.

P:= proc(n::posint)
     to n do
          rtable(1..2, 1..2, storage= triangular[lower], subtype= Matrix)
     end do
end proc:

Q:= proc(n::posint)
     to n do
          Matrix(2, shape= triangular[lower])
     end do
end proc:

CodeTools:-Usage(P(100000)):

memory used=16.79MiB, alloc change=0 bytes, cpu time=187.00ms, real time=199.00ms

CodeTools:-Usage(Q(100000)):

Kitonum's Answer shows exactly what he wrote to create the plot. The lines in boldface are the literal code.

The normal distribution's CDF is not an elementary function and is usually expressed in terms of erf. What representation were you hoping for? 

@ncncnc23

My advice was intended for when A was created via output= plot, as it was before. But you've changed that to output= sequence.

@ncncnc23 

It seems to me like that would be a rather crowded plot. But if that's what you want, simply do

plots:-display(A); 

Speaking of tag management, I think that users with global editing powers should be able to remove garbage (i.e., nonspecific) tags from the tag database. The one that irks me the most is "query," but there are numerous others. 

@ncncnc23

To see the 34th plot, for example, just enter 

A[34]; 

If you decide on some format that you would like to use to see all the plots at once (such as animation or a tableau), then we can work on that.
