Hello,

I am trying to run maple file for k=1, k=2 ....

My do-loop did not work. What I would like to do is to solve the ODE then have new inc and solve it again.

I should have U(405) then U(770) ....

> restart;

> with(DEtools); with(plots);

> lambda := 0.1; delta := .5;

tau := 40;

> for k to 3 do 365*k end do;

> ode := diff(U(t), t) = -lambda(t)*U(t)*U(t);

> inc1 := U(0) = 100;

Hi everyone.

I have a problem with Maple 15. I have an equation, but when i write in into Maple, it says: "Warning, solutions may have been found". I don't know what to do. I've tried to solve it on paper, but without any luck. Could someone please help me?

Equation: ((x+1)²/3) - ((x+2)(x-2)/2) = ((x+3)/2) - ((x-2)²)/6) 

or when i copy paste from Maple...

(1/3)*(x+1)^2-(1/2)*(x+2)(x-2) = (x+3)*(1/2)-(1/6)*(x-2)^2

Hello my brothers and sisters..

Well, i have to say im really lost .. i have tried a lot but cant figure this out.. i cant open my math task and it only says "there was problems during the loading process" please help me guys i need this i have spent hours on this. and by the way its maple 15 on a mac.. thank you guys..

I'd like to hear a sound alert when Maple 15 (64bit version, on Windows 7 64bit) finishes the execution of a command.

For example, I have a very lengthy function to simplify. I use

simplify(function,size)

but it takes too long. It would be very helpful for me to hear a sound when this simplification finishes so that I can come back to see the result and go on.

Hey, I'm just starting to work with maple and I have no idea how i could restract a,b,c,d,e,f,g,h,i in a 3x3 matrix

I wrote a module that has quite a few commands in it. I want to make a help file for it so that when you type something like ?mypackage, something like this will pop up! thanks in advance!

Hi

i need help

Hi, I use maple 12 for mac, I have an exam at 9am, it's almost 3am and my whole exam notes (open "maple" exam, as opposed to open book) have just corrupted.

PLEASE HELP ME.. :(

if maple cannot factor something, does it mean it cannot be factored for sure?

i have a really really long univariate polynomial with coefficients that are also variables (a[0],a[1] etc), is there any tips on how to factor this monster?

thanks in advance!

Can someone please help me with the Maple language in solving the following equations?  I have already solved them by hand but I am new to Maple and am having difficulty with the coding language.  Here are the problems:

1.  Graph the parametric curve x=2t-pi*sin(t), y=2-pi*cos(t) from 0 to 20.  The curve forms loops, determine the arc length of one loop. 

2.  Graph the rose curve r=sin(4theta) in polar coordinates.  Determine the area of one pedal. 

This is the eq I am trying to solve

pde1:= diff(Phi(r,t),t,t) = (-(diff(Phi(r, t), r, r))*r^2-2*(diff(Phi(r, t), r))*r+2*(diff(Phi(r, t), r))^2+4*(diff(Phi(r, t), r))*(diff(Phi(r, t), r, r))*r+2*(diff(Phi(r, t), t, r))^2*r^2)/(r*(-r+2*r*(diff(Phi(r, t), r, r))+4*(diff(Phi(r, t), r))));

with initial conditions..

z=1000;

IC:={Phi(r,0)=Piinitial,D[2](Phi)(r,0)=0,D[1](Phi)(0,t)=0,D[1](Phi)(z,t)=0}:

pdsolve runs and returns the module..

Hi,

can you help me, I want to make a convolution on this :

 But I really do not know how to deal with the diff...

Thank

Sorry for my english

Hello,

I have downloaded the quaternion package in Maple but I can't figure out how to plot them. According to the help page I need a package 'with(Plots)' (with a capital P for plots). Has anyone had any success in plotting quaternions? I'd really appreciate some help.

Thank you.

Hello,

I am very new to maple. I am trying to determine x, y, z and the intersection the following tori:

((x * cosθ _j+ y * sinθ_j -r)² + (x * sinθ_j - y * cosθ_j -r)² + z² + a² - b² )² - 4 * a² * ((x * cosθ _j+ y * sinθ_j -r)² + z²) <= 0

for j = 1,2,3.

I have a peace of a programm of finding the shortest way in graph! And I need to animate this way! Help please! 

This is a code of programme:

1, 2, 3, 4, 5, 6

> [5,6],[1,5]],weights=[12,16,20,11,15,13,14,26],G):
