Maple is usually very fast, and I recently upgraded to 2022 edition. 

However in the new version, I tried to solve this equation here. 
solve(1 + 0.15 = (1 + r__x)^1.28858)

It took Maple 2022, 46 to 118 sec to come up with a solution to the above. I run Windows 11 latest version, have 32 GB of ram and dual NVME disks in my laptop. 

Windows 11 uses almost a Gigabyte of memory do this calculation. 

So what could be wrong? Is mserver not working proberly?

solve(9*log10(x + 1) = root[3](x), x);
Warning, solutions may have been lost

How come maple can't solve this equation with the standard command?

And what can I do to find all the solutions?

EDIT: For some reason I can't repply.
@Kitonum , thanks for answer.

I suspect there may be more real solutions than the ones in your example, but if I change the range some of those in your example goes missing. Is that a bug?

Thank You

Hi,

I want to extract the highest linear and non-linear terms in an equation without their coefficients. 

How I can do it?

For example in the following equation, the highest linear and nonlinear without coefficients are diff(u(T),T$3) and u(T)*diff(u(T),T), respectively.

w*a*diff(u(T),T)+a*u(T)*diff(u(T),T)-(b^2)*a*w*diff(u(T),T$3)=0

Thanks in advance.

How can the Cartesian Product of sets be implemented recursively in Maple?
Let k be a positive integer and S_i , i=1,...k be nonempty finite sets.
How can M_k:=S₁ x S₂ x ...x S_k be constructed with Maple by recursion?

Maple 2022:

It appears that one can use push_back() with an empty DEQueue(), but not push_front().

Since the queue is double-ended and empty, this doesn't make much sense to me. So should this be considered a "bug"?

I have just started using the GR functions available in Maple and have struggled to implement locally flat coordinates whilst using an arbitrary metric. I would like Maple to know that the first partial of g_ is 0 but that the second may not be. This knowledge would help simplify down some of the bulky expressions for the Riemann tensor in terms of g_. Any suggestions would be great as I have very little background knowledge with the submodule.

Thanks!

restart;
g := 9.81;
with(DEtools);
with(plots);

odeplot(dsolve({diff(x(t), t, t) = 0, diff(y(t), t, t) = -g + y(t)^2, x(0) = 1, y(0) = 0, D(x)(0) = 0, D(y)(0) = 0}, numeric), numpoints = 1000);

Hi, do you know why this plot is ragged? and my second question do you know how to get a single function x(t) or y(t) from this numeric solution instead getting parametrization plot [x(t),y(t)]? Thanks in advance.

Hi Im not sure how to solve this issue, I am new to maple and can't figure out what is going wrong. Any help is very much appreciated.

Thanks

I am trying to find the solution (\Psi) as f approaches zero. However, after applying the limit the solution becomes zero. See the attached .mw file.limit.mw

A question by @Shameera  I was working on has disapeared meanwhile.
It was related to this previous thread 233822-How--To-Solve-This-Equation-By-Using but has not been displaced in it.
Did a regolaror do this or was it  @Shameera ?

Why do I get 2 wrong answers here?

I see that they are all false but the last answer is close enough for my purposes

I have a routine which returns a certain result. In the simplest case the result should be p[[1]].

The result is indeed p[[1]]. However, when I ask whether the result is equal to p[[1]], Maple says false.

Why does is not recognize these two things as being equal?

I have seen that this is possible (for example in the example:  2-D Flexible Spin-up Beam).

When I copy an image to the Windows10 clipboard it does paste to other applications but not to MapleSim. Instead, I get an audio notification from the system that is played on other instances when an action cannot be performed.

Within MapleSim copy and paste works (also between models). However, copying an image from a Maplesim Model to another Windows App does not work.

Can someone confirm that pasting images works in recent verions?

(Clearing the Clipboard removes images copied with MapleSim.

Observed on 2 Windows 10 installations with the version 2022 and 2021.)

I want to integrate the function int(1/(A^2 - B^2*cos(t))^(1/2), t = 0 .. 2*Pi), I get the correct solution, but I want to prevent all the "if" statements from appearing. I have tried to use "assume" but the if statement still does not disappear.
