I execue flow command,but it doesnot generate;

how i fix it?

Warning, the function names {diff, theta1} are not recognized in the target language

Hey guys !

I wondered if it's possible in maple to hundle functions, for exemple to know if a function is a sum or a product of two functions.

Is there a function like this : sum (\x -> x+3)  -------->  [(\x -> x), \x -> 3] ?

If I ask this, is because I want to know if it's possible de rewrite the function `deriv` or `integrate` or `simplify` by hands, without using the native functions.

Problem. Let A(-1,3,-2), B(-3,7,-18), C(2,-1,-3) be three points and (P):

2*x - y +z  + 1 = 0 be a plane. Find the coordinates of the point M lies on the plane (P) so that MA^2 + 2MB^2 + 3MC^2 obtain the minimum value.

This is my code.

restart: with(geom3d):
 A:=:  B:=:  C:=:
M:=: o:=:
eq:=solve([seq(o[i] = (A-M + 2*(B-M) + 3*(C-M))[i], i=1..3)]);
point(T, -1/6, 7/3, -43/6); # put T by my hand
plane(P,2*x - y +z  + 1 = 0,[x,y,z]):

Hi!

how I import maple code in matalb for matlab simulink?

Hi,  I have and integral its results contains Beta function and hypergeometric function.
I found a difficulty to program the hypergeometric function with Maple 13.    is any one can solve this problem
where 

∫₀^{(π/2)}((sin^{α}xcos^{β}x)/(√(1-k²sin²x)))dx=(1/2)B(((α+1)/2),((β+1)/2))F(((α+1)/2),(1/2);((α+β+2)/2);k²),α>-1,β>-1,∣k∣<1

The problem in written...

simplify(sqrt(a+sqrt(b))*sqrt(a-sqrt(b))-sqrt((a+sqrt(b))*(a-sqrt(b)))) assuming a>0,b>0,a>sqrt(b);

It's mathematically zero but it does not return zero.

How can I simplify it?

Problem. Let (P): 2x -y +2z + 9 = 0 be a plane and two points A(3,-1,2), B(1,-5,0). Find coordinates of the point M lies on (P) such that scalar product of two vectors MA and MB obtain  the minimum value. 

Hi,

I have a rather burly system of PDE that I need solved in maple.  It's a little complicated to explain the set-up, but I am solving for some coefficients of a function expansion where each coefficient is solved in terms of some other known functions. 

Basically the problem is the technique and code works perfectly for another application, but it fails me here.  For one, when I try rifsimp(%,[a[0](x,y,t),b[0](x,y,t),c[0](x,y,t)]), it runs for...

How do you make a straight line defined over an x interval?

Plase write for me a code for the following problem:

Let (d): (x-1)/2 = (y+2)/1 = z/1 be a line and

(P): x + 2y -z - 3 = 0 be a plane.

Write the equation of the line (Delta) lies in the plane (P), perpendicular to the line (d) and the distance between (d) and (Delta) equal to sqrt(2).

Hi..I need to plot the slope field for a diffEQ and having problems. I have a Maple 14 program that I just had to reinstall due to a virus and hoping that isn't the problem.  I'm very new to Maple and I'm not a good programmer, so any light you can shed on my problems would be much appreciated.  When I enter the problem, I don't get any error message or anything...just a blank return!  This is what I tried:

with(DEtools):

DEplot (diff (y(x...

Hi All,

I am trying to solve a simple problem but don't know how to do it in MAPLE 14.

A:=[1,2]

B:= [3,4]

is there any possible way to write 

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

C should have both value of A and B Matrixes.    I want to generalize so any command in MAPLE 14 which can do this operation.

Thanks in advance

Dear Maple Primes

I need to plot two functions but I need one of them to only be defined over a certain range. Here's the example:

I'm entering many 1 row x 2 column tables mixed with text in a document.  In all cases I don't want the lines around the cells and I want the text in the cells to centered rather than left justified.  

Is it possible to change the default properties of tables rather than having to change the properties of each one after I enter it?  This is Maple 14
