@DSkoog , Thanks,  I know of the rtablesize, but I didn't know that the structure had to be converted from it's original structure form to view other columns.  The GetHeaders I think will work for my purposes.

@vv thanks. 

So if a solution can eventually be found shouldn't Maple exhaust all methods behind the scenes to give a solution?  That is probably the holy grail coding of any CAS system

@Kitonum thanks for a solution

@acer I see.  I didn't come across anything about him mentioning that the fails didn't mean the CAS couldn't actually solve the problem.  I falsely undertook his findings as hard and true (probably in most cases other people as well). 

I think it basically boils down to not being able to do this

int(1/(sqrt(x+exp(x))),x)

 

I tried with subs which partially worked.  But as soon as I invoked the sort command the order jumbled out of order, until I used the restart command which makes my idea somewhat useless.

 

@Axel Vogt indeed, a one function approximation is probably enough, but as you say it looks more like 2 or even 3 functions.  I wonder if the op could let us in on what the values are supposed to represent.

On top of a wave increasing in amplitude it does appear the there is some underlying fluctuating superimposed wave.

I don't know, but I wonder if windspeed data could be pulled from https://earth.nullschool.net

Two thumbs up for the clustering and geographic additions!  This new edition looks like it will be a joy to explore.  I've been lost for innovative ideas in Maple the last couple of years, I hope to apply some ideas in the new Maple and to compile some things to apply and to improve on.

 

@Bryon thank you

It seemed like an interesting enough question - homework regardless - it does appear the question was mistakenly identified as spam.

Can the administrators repair?

As a relatively avid maple user, some time ago I required the use of Geometry expressions, to find an equation based on various angles and lengths with respect to something else.  I could have done it by hand, but of course it was easier to draw the pictures in Geometry expressions.  This could not be done so easily with Maple I recall. 

Can you present a screenshot?  Also provide Maple version and OS.  Probably just a restart will suffice.

It is something that is impossible to occur.

@ Kitonum - It does not work in Maple 12.

Error, (in pdsolve/sys) unable to handle PDE problem subject to boundary conditions {u(0, y) = 0, (D[1](u))(0, y) = 0}

However it does work in Maple 18.  Therefore this is a regression bug that exists in 2016.1  No one has been able to confirm if it exists in 2016.0 or not.  I will be able to confirm this tomorrow.
