Hi, I am currently enrolled in a class which uses Maple 12.  I have looked through all the FAQ and Help topics by using their search functions.  I still not have the command to find the Domain and Range of a function.  Advance thanks for any help which is appreciated

Hello,

I need to export animation as a gif picture with different speed of animation.

I use plotsetup(gif,  ... but I do not know how I could do it.
 

Please help me.

Thanks

Hello Folks ! I'm running Maple 11 on Mac OS X Leopard (latest version 10.5.6). I've found what I think is a bug in Maple: when doing operations on large polynomials, like multiplication or factorization, the result is correct, but some ghost exponents show up on fractions or even plus/minus symbols. In the file I've attached you will see this in the last two results, in which a 4 exponent shows up over the 1/8 and +/- signs or even over some parenthesis. Maple doesn't seem to get confused wi

Hi,

I'm trying to extract some coefficients from a symbolic determinant but it's not working. I tried every option presented on Maple help but couldn't get it to work:

1. How set these varibles and unknowns ?

for example

q := {l2s = n+l2[0], ds = k+d[0], l1s = m+l1[0], m+n = k}

I just want know the ds expressed with the varibles: d[0], l1[0],l1s,l2[0],l2s

How ?

solve(q, {k, ds}) and solve(q,{ds})

doesn't work.

 

2. Another question. If I get the result sets {a=..., b=... }, how can I get the expression of a or b. As we know, the sequence of the a and b in the set is not allways the same way. It may be {b=..., a=...}

graph the vector field F and the curve C to guess whether the line integral of F over C is positive or negative or zero. then evaluate the line integral F(x,y) = (x/sqrt(x^2+y^2)i + (y/sqrt(x^2+y^2)j C is the parabola y =1 +x^2 from (-1,2) to (1,2)

plot the gradient vector field and the contour map of f f(x,y) = sinx + siny

can anyone help me to plot that vector field of F(x,y) = (y^2 -2xy)i + (3xy -6x^2)j

the cylinder r = a*cos(O) cut out of the sphere of radius a centered at origin. any help. thanks

Graph the solid bounded by the plane x+y+z =1 and paraboloid z=4-x^2 -y^2, and find the volume. here what i tried, but i cannot get the volume > f := x+y-1; > g := 4-x^2-y^2; > plot3d({f, g}, x = -2 .. 2, y = -sqrt(1-x^2) .. sqrt(1-x^2), axes = boxed); V:=Doubleint(g-f,y=-sqrt(1-x^2)..sqrt(1-x^2),x=-2..2): V=value(V);

 

The below code is quite good but one thing that is annoying is that we get the same trajectory all the time.

Any suggestions on how this can be fixed ? ( when the simulation starts over I would like to have a new trajectory)

I tried to put the random variable inside the procedure but the result was that all trajectories are changing all the time, which

was not really what I wanted .....

 

Hi everyone.

I have an assignment due in my computing class. However, I'm stuck on these 6 questions. Any help would be greatly appreciated. Please show all work, step by step. Unfortunately though, I can't use Maple shortcuts like "sum" to sum the terms in a sequence, so try not to use those.

Thanks in advanced :)

hej guys,

i have a 4x4 matrix, each element containing a complex function, depending on 'x' or whatever.

In fact i want to compute the 'eigenvalues' of the realpart of this matrix.

 

So far i tried:

assume(x,real):

then taking the real part of each matrix-element(function) on it's own, building a matrix again finally.

eigenvalues( ) gives me "Error, (in content/polynom) general case of floats not handled".

 

So yes, i appreciate any reply, thx in advance!!

I would like to calculate the double integral

int(int((f(rcos(teta),rsin(teta)),r=1/sin2(teta)-cos(teta)..2sin(teta)),teta=pi/8..pi/2)

Where f:=(rcos(teta),rsin(teta))->1/(2sqrt(r^2cos^2(teta)+r^2sin^2(teta)))r

 

But i only manage to calculate the inner integral on maple. The assignment says that there should be an answer just that it will be very long but an answer where the second integral is not calculated is not an answer?
