I am fairly new to Maple 10 but not to math and graphing calculators. I was wondering if anyone knows how to get Maple to calulate a line integrals or even farther, closed loop intergals. I tried a bunch of different things with the contour integral but I dont even know if that is an operator but just a symbol instead. Thanks in advance to anyone who can help me out!

Is this a way to convert a routine in Maple internal format back to the human-readable format?

Thanks

hi, i don't know maple at all and i need to figure out how to solve this sytem of equations that model predator prey systems in maple but i get an error when i modify this code > e1 := diff(x(t),t) = k*x(t) - a*x(t)*y(t); > e2 := diff(y(t),t) = -r*y(t) + b*x(t)*y(t); to fit this equation- dx/dt = 2x(1-x/4) - xy dy/dt = -3y + xy x(0) = 1 y(0) = 1 if anyone has time to tell me what i can do to get the equilibrium points, the solution and the table of values for this system, i would be grateful

I was wondering if someone can help me solve a problem of kirchoff's law using maple, heres the problem:

Use maple and Laplace transform to find the charge q(t) on the capacitor in an RC series circuit with the following conditions; graph q(t) on the interval 0<t<6 and use the graph to estimate the time and value of the maximum charge

q(0)=0
R=50 ohms
C=.01 farads
E is a piecewise where 1<x<3 = 100, everywhere else is zero
I'm assuming that since nothing is said about the inductance in the initial conditions, L=0

heres what i got so far:

>i(t):= diff(q(t),t);
>KirchoffLaw:=E[R]+E[L]+E[C]-E[emf]=0;

Does anyone know how to go about attempting this problem with Maple10 ? The question is the last line in bold type, and I tried to include as much relevant information as possible. To correct an error the second partial derivative should be with respect to time "t", not displacement z. so it should be (1/v)*(d^2/dt^2)f(z,t). sorry about the mistake. thx, Dan View 285_problem9.4Emag.mw on MapleNET or Download 285_problem9.4Emag.mw

Hi, How can i compute the F2 Appell Hypergeometric Function using Maple? Can i write F2 as a function of the F1 appell function? Thank you. Appell Functions: http://mathworld.wolfram.com/AppellHypergeometricFunction.html

I have a function: fx:=5*x^4+16*x^3-24*x^2 for which to calculate roots I wish to reformulate fx to (x^2)*(5x^2+16x-24) Which command do I need to give maple to obtain this result?? Thanks in advance

How do I evaluate a result for a certain value for a variable? For example, int(sin(x),x) get me cos(x) in Maple. How do I ask Maple to evaluate cos(x) at , say, x=Pi/8 ? Thanks in advance.

Hi, I have plotted the following triangle PLOT(POINTS([(-2,-4)],[(1,3)],[(2,-2)])); How do I get maple to connect these points? Is this the right way to plot a triangle, or is there a better way?? thanks in advance

ok, my first question, and as I only started using maple about 1hr ago, its probably rather a simple solution that I've missed. I'll tell you what i'm trying to do, and what I've tried so far. I've run some code which has given a formatted output of a lot of numerical data, in 4 columns (which I may wish to call x,y,T and P if I can). I wish to import this data into maple, so that I can eventually plot contour plots with it of T on a x and y grid, and P on an x and y grid. Having tried to use the readdata command to read the file in, I got a lot of row vectors. However I then couldn't find out how to reference specific values in these vectors to allow me to assign them to variable values, or maybe just directly plot them. I tried using the importmatrix command to see if that gave anything, but that failed entirely.

I know I haven't figured out all the limitations of Maple yet to avoid all the "gotcha"s but this should be straightforward, right? with (VectorCalculus): b(x,y,z) := VectorField(

Hi all, Given two functions f(x)=x^2-1 and g(x)=2x+1 we can plot the following command restart:f:=x^2-1:g:=2*x+1:plot([(f),(g)],x=-2..4,y=-2..8); We have a local extreme of -1. Which command should I use to give me the local extreme where -2 <> 2?? Thanks in advance

find all the prime numbers from 1 to 100 using if condition and loop bye maple 9.5

Hi, Given a function f(x)=x^2 i would type the following command restart:f:=x^2:plot(f,x=-10..10,y=0..10); how do I get the graph to show f(x) as a dotted line?? thanks in advance Robert

Hi to all.. Maybe a beginner's question: How to configure Maple to automatically execute a worksheet as soon as it is loaded? I use Maple 8 on Windows XP and don't want to do Edit/Execute worksheet. Maple is opened via an external batch file. Also, that worksheet produces a graphic file. How to modify the worksheet so that the graphic is automatically saved in a c:\Picture directory after being produced? Thanks for your kind help, Pierre
