Hi!

Probably trivial, ...but how to set up a slider in degrees.
I'd like to use degrees instead radians in expresion ...from some reasons.
Help will be apreciated :-)

Dear Maple users

The formula f = c/λ is expressing the frequency in terms of the velocity of light  c and the wavelength λ. Lets say given not just one wavelength, but a whole list af wavelengths. The values have units attached. I wonder if there is an elegant way to have Maple calculate the all the frequencies, eventually delivering them in a new list?

I want the units of the output reduced to SI-units,...

Hi

I've got a small problem:

how can i calculate with units AND show variables and its untits on both axles of a plot in the same worksheet?
and is there a way to give the range for each axle at the same time too?

This one only works for one axle:

restart;
with(Units);
d := 40*Unit(m);
a := .25*Unit(m/s^2);
x := d+(1/2)*a*(t*Unit('s'))^2;
plot(x, t = -10*Unit(s) ..10*Unit(s),useunits);

has anyone any ideas how to show "x[m...

Hello,

I would really appreciate some help. I am trying to use maple as a document of engineering analysis and calculations (like I would do in MathCAD), can maple handle such things. I seem to be having problems with the formatting. For example my units and outputs seem inconsistent, where am I going wrong. I have uploaded a file belwo for some advice please.

Also when I define a variable and then change the variables value can I get all the equations which...

I would like to set an axis to logarithmic scale, after having loaded the Units[Standard] package.

The command is:

plot3d( function(input), x=-1..1, y=1..1, axis[3]=[mode = log] )

Confoundingly, the error is:

Error, (in plot3d) expecting option mode to be of type identical(linear, log)
 but received Units:-Standard:-log

So the problem is that with(Units[Standard]) hijacks all occurences of log and replaces them with...

EDIT: I have figured it out (somewhat), so nevermind!

I wrote this in my AddSystem:

However for output that should be unitless, I still get units (which can be cancelled), like this:

The Units package includes various units that are called ton/metric ton/tonne/short tons but not long tons (LT). A long ton is equal to 2240 pounds of weight and is part of the imperial system, so it is also know as the "imperial ton" or the "weight ton".

This unit (the long ton) is used extensively in naval architecture and ocean engineering. I would hope that you consider adding it into the next update of the Units package.

Or perhaps, it would...

Dear Maple Users

I was looking forward to having the Units package improved in Maple 15. Units are indeed converted to SI Units when direct calculations are made. It is a disappointment though that this conversion doesn't occur when solving equations as the example below show:

Unfortunately Maplesoft mix up their announcements for news in version 15 of Maple with...
