Hi .please help me for solve this nonlinear equations , that attch below

thanks a lots.....

dsys3 := {8*(diff(f2(x), x, x, x, x))+9*(diff(f2(x), x, x))+10*f2(x)+11*(diff(f1(x), x, x, x))+12*(diff(f1(x), x))+13*(diff(f3(x), x, x))+14*f3(x)+f3(x)*f3(x)+(diff(f3(x), x))*(diff(f3(x), x))+(diff(f3(x), x, x))*f3(x) = 0, 16*(diff(f3(x), x, x, x, x))+18*(diff(f3(x), x, x))+19*(diff(f3(x), x, x))+22*(diff(f1(x), x))+23*(diff(f1(x), x))+24*(diff(f2(x), x, x))+25*f2(x)+26*f2(x)+27*f3(x)+29*f3(x) = 0, 2*(diff(f1(x), x, x))+3*(diff(f2(x), x, x, x))+4*(diff(f2(x), x))+6*(diff(f3(x), x))+7*f1(x)+(diff(f3(x), x, x))*(diff(f3(x), x))+(diff(f3(x), x))*f3(x)+(diff(f3(x), x))*f3(x) = 0, f1(0) = 0, f1(1) = 0, f2(0) = 0, f2(1) = 0, f3(0) = 0, f3(1) = 0, ((D@@1)(f2))(0) = 0, ((D@@1)(f2))(1) = 0, ((D@@1)(f3))(0) = 0, ((D@@1)(f3))(1) = 0}; dsol5 := dsolve(dsys3, 'maxmesh' = 500, abserr = .1, numeric, range = 0 .. 1, output = listprocedure)12.mw

Hi everyone,

I have a great problem with the evaluation of following definite integral

> restart;

> int((t-x)^2)/(1+2t+(1/2)t^2-ln(t^2+2t+2)t-ln(t^2+2t+2)+arctan(1+t)t^2+2arctan(1+t)t+ln(2)t+ln(2)-(pi/4)t^2-(pi/2)t)^2,t=0..x)

I have tried different classical commands but Maple doesn't give an answer. Probably, it's just a silly fault.

Does anyone knows how to solve it?

Thanks.

Hello everyone,

How can unknown values in boundary conditions of system ODEs be determine by using shooting technique. See the work sheet here Sht.mw

Thanks.

Hello;

I wish to express a tensorial equation or expression a simplified vector form.

In the worksheet attached, I was trying to express Maxwell Equations in the familiar vector form from the tensorial form, using the tensor.

But I cannot achieve the familiar tensor form. If someone can give a hand, it would help me a lot.

Hi, I know this has been asked ( and answered before) but when I installed this package and pressed ?globalsearch the help page is void.how do I get it?

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.

How to solve delay differential equations with Maple?

Example:

diff(x(t),t) = 3*x(t)^2 + 0.3*x(x-0.03)

y'(t)=1-y'(t-y(t)^2 /4),      t>=0

with initial function

y(t)=1+t,   0<=t<=1

please solve

Sorry for making such a rude, big question. I have to solve these equations, but it's impossible ofcourse with my bad mathematics and even maple skills. Somebody help me pleaseㅠ_ㅠ

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!

please write a program on matlab or maple for this dde

y'(x)=-y(x-pi/2)       0<x<=10

y(x)=sin(x)       x<=0

tau=pi/2

IT IS URGENT PLEASE

Dear, I want to the expression for any r and s. Please help I am waiting your quick responce

Hi,

I am experiencing some problems with the plot3d command. It does not return a nice 3d-graph, but just a bunch of dashed lines. I have entered something like this:

with(plots):

plot3d(x*y,x=-1..1,y=-1..1);

I am using maple 17 on windows 7

Thanks in advance.
