Use a change of variables to find the volume of the solid region lying below the surface f(x,y)=(2y-x)^4sqrt(x+y) and above the parallelogram in the xy=plane with vertices (3,5) (2,6) (10,10) and (11,9)

Graph the 'ice cream cone' formed ny the upper half of the sphere x^2+y^2+z^2=16 and the cone z=sqrt(x^2+y^2) using maple, and find the z-coordinates of its center of mass.

Graph the solid common to the cylinders x^2+z^2=4 and y^2+z^2=4 using maple and find the volume of the region common to the cylinders.

I'm suppose to graph the first octant portion of the surface z=4-x^2, 2≤y≤5 using maple and find the volume of the solid over the xy-plane and under the surface.

Hi
I wrote a loop which is too long but I need its continuity so I wrote all of them in one loop.
The problem is too much time is needed to run it,even maple cannot run it.
I do not know whether my software has a problem or the way I wrote the program is wrong.
I attached the file.
thanks

Hi, everyboyd I wan to draw a vertical line at theta:=Pi  for any function.

How can i do it.

Amr

I have a matrix m with 9 rows and 4 columns and when I enter the command below I get an error message:


num := product((z-(m[s,1]+I*m[s,2])),s = 1..9);
Error, Matrix index out of range

However, there is no problem if I use brute force:

any of the numerical factors that multiply the successive terms in the expansion of an expression of the form  (x + a)^n,  for integral n,  in accordance with the binomial  theorem. These are any terms of the form
               ∑x^(n-k)*a^k*binomial(n,k)


how to get it.

convert((x+a)^n,Sum,x)


but ,i get a anwer that i don't want

Dear all!

I wrote a program but when I run it I get an error as: " can not evaluate the solution further right of ..., maxfun limit exceeded ". I tried some ways to work around it, for example I tried "maxfun=500000" and more. Also I tried "maxfun=0", but they don't work. How can I solve my problem?

O.K. Isolved this problem myself. We can solve such a problem in two different ways. 1.by adding the expression "method=mebdfi" and 2. by adding expression "'stiff=true'".

Like in the version 7 where that variable didn't exist.

Pleaes visit the attached file and tell me what should I do. Thanks a lot.

Hello all,


This is my first time posting here; I usually find answers to all my questions by searching patiently but I was unsuccessful with this particular issue.


I attend an introduction Maple class and i'm building an animated bike as project. I was already rather comfortable with Maple so i'm trying to show off a little by adding lots of cheesy details to the scene, even if unnecessary. However, some objects such as the sky, which i would like to...

Hi all,

I have this function:

restart:

I2:=g->(200*g)/sqrt(0.04+g^2);

plot(I2(g),g=0..1); 

plot(I2(g),g=1..0);

Those two plots give the same result.

Is it possible to invert the x axes to start from 1 ?

I also tried this below, but the result is as above.

x:=seq([g,I2(g)],g=1..0,-0.02);

pointplot([x],style=line);

Thanks

Hello everybody,

I have this equation J:

> J := Matrix(2, 6, [[j41, j42, j43, j44, j45, j46], [j51, j52, j53, j54, j55, j56]]);

it's a 2 times 6 matrix made with the results of other equation, each one of those small j's are long analytical terms.

Later I want to generate a Matlab code of J using this:

> Matlab(J, resultname = "j4", output = "file.m", optimize);

I use the optimize code at the end because then I avoid getting...

Hi all,

To share a maple document, I found this Maple help.

To share worksheet content:
1. In Maple, open the worksheet that contains the content you want to share.
2. If you want to share a worksheet selection, select the text and objects in the worksheet. If you want to share an entire worksheet, you do not need to select any text or objects in the worksheet.
3. Expand the MapleCloud palette.
4. From the drop-down list in the palette, select...
