Yes I agree, his applications are always worth looking forward to.

How many versions back does this issue go?

Sounds like he is using the 64 bit version of Maple 15 or Maple 16. 

The shipped version comes with both 32 bit and 64 bit.  The 64 bit version of only Maple 15 and Maple 16 have limited Finance package use but the 32 bit version has full functionality of the Finance package.  Install the 32 bit version and you will be able to use the finance package without error.

There is some good information here, no need to delete your question.

@rollermonkey As Carl and Acer have provided your solution, use with(plots) and not with(Plots) the error message you posted shows you are capitalizing plots when it is not valid.

Your G=plot3d([x,sin(x),2sin(x)+cos(X^2)], x=-2..2,color=black)   will produce an output but it won't assign the output to anything which is why you come across the error when you try to use G later on. 

withPlots returns withPlots but Maple is only returning your input and hasn't done anything with it.  If I type Hello Maple says Hello back but there's no actual execution of commands just a mirrored return which is why you see a blue syntax on the use of withPlots.

If you provide the exact error message associated with your use of := we will know how you are typing it in.  It is quite possible deducted above that you have inserted a space between : and =

Just remember to restart or start a fresh worksheet, it could be a bad install but most likely the syntax.

@gkokovidis whoops, sorry about that I mixed it up with another document Maple 18 yes.  I updated the title of my previous post to reflect the correction thanks gkokovidis!

@Preben Alsholm Thanks for your help I appreciate your work.  Currently I'm getting a warning..

Warning, cannot evaluate the solution further right of 1.2176265, event #1 triggered a halt

I think that's expected.  Yes I realize it's adhoc, eventually I hope a solution can be found where the animation appears natural and Maple can simulate the ball rolling to stop as close to reality as we can.

So I'm not sure how to modify the ball application so the ball rolls to a rough stop in one of the troughs?

@Joe Riel A CR:=0.3 will slow the ball down enough to stay within the field of view. 

But that doesn't matter expand the frame view and when the ball slows down enough it doesn't just roll along the surface.

Perhaps there is something about the surface normal that is causing the problems.  Any ideas? Anyone?

The other issue that exists is when parameteres are set to see the ball settle into one of the valleys the ball drops out, it doesn't settle to rest.  Is the issue internal or did something get missed in the equations?

@Joe Riel The one in the help under math apps -> engineering & applications.

In Maple 15 and 16 the finance package was only available in the 32 bit version.

Are all functions and packages available in the 64 bit version of Maple19(Maple 2015)?

I am lost when it comes to using api's and wrappers.

However I don't think an API or wrapper is necessary.  Perhaps there is another website that will allow HTTP from within maple to work without any javascript voodo.

The idea was to export text from the worksheet using some sort of HTTP or URL call from maple

If I can get the text above to work then it shouldn't be a problem.  The problem is I am unable to get that simple text above to work in any free translate websites to return translated text.

Can you provide a simple code that works to return some simple text translation within maple?
