Dear I want to define a general operator D for Fractional derivative whose behave like this

(D^alpha)(t^beta) = GAMMA(1+beta)*t^(beta-alpha)/GAMMA(1+beta-alpha)

Hi,

I just started to use Maple and I have a question if there exists in it an equivalent function to Mathematica's FindInstance? In general, I have an inequality and I would like to find few first solutions to it.

We find recent applications of the components applied to the linear momentum, circular equations applied to engineering. Just simply replace the vector or scalar fields to thereby reasoning and use the right button.

Why does my Maple 2015 constantly pause to redraw symbols in pinned palettes?  Really seems to slow down my use of the program.  Had this problem in previous versions also.  Using OSX Yosemite latest version.

Hey there!

I uploaded a solid drawing from a CAD software (like solidworks, inventor, stl files, etc) into Maple using plottools:-importplot("drawing.stl"). 

Also, I know Maple can give me the normal vector (and point of intersection) using line and intersection commands, for example.

Now, is it possible to find a point of intersection (and the normal vector at that point) of a line that crosses the uploaded CAD solid?

I guess that to accomplish that, it would be necessary to somehow "map" the solid and that's the part that I am lost.

Many thanks!

In Maple 2015, on windows 8.1 64-bit the command
series(2*x*(x-y)/y, y = 0, 3);
gives

which is incorrect. The answer is


You can notice the minus sign in front the the -2x is incorrectly typeset, which makes me wonder if it's a bug in the typsetting program and not series itself.

Please fix asap

Int(ln(1+sqrt((x+1)/x)),x);

value(%);

Does not work.

Int(ln(2+sqrt((x+1)/x)),x);
value(%);

Works.

But with some effect,

Could this possibly be improved in the next release?

Int(piecewise(t < T1, exp((1/2)*t*(1+2*I-I*sqrt(3))), t < T2, -1000*exp((1/2)*t*(1+2*I-I*sqrt(3)))*(-1/1000+T1-t), T2 <= t, -1000*exp((1/2)*t*(1+2*I-I*sqrt(3)))*(-1/1000-T2+T1)), t)

Suppose I have a file, test.txt, which the content is

2
2 0.0 0.0 0.0
1 0.0 0.0 1.6

I would like to save 

Z:=2;

C[1,1]:=2;C[2,1]:=0.0;C[3,1]:=0.0;C[4,1]:=0.0;

C[1,2]:=1;C[2,2]:=0.0;C[3,2]:=0.0;C[4,2]:=1.6;

However, if I use readdata("...",4), seems it do not work.

Is there any flexible command in maple can readfile with different column? Thank you very much!

Consider the equation

eqn1:=5^(2*abs(y-1)+2) = (1/15625)*625^abs(y-1);

and note that

eval( eqn1, y=-3);
eval( eqn1, y=5);

both return valid solutions. So why does

testeq(eqn1);

throw a numeric exception.

Given the manual description of testeq(), I would expect it to return either true or FAIL - but not a numeric exceprion!!!!

Any ideas?
