MaplePrimes Questions

I am using Maple 7 and displaying computations within a spreadsheet for more simple display. One area I have been stumped with is using the if statement within a spreadsheet cell. Something as simple as: if FAIL then 3 else 5 end if works great at a prompt but gives me a "System error," within my spreadsheet. Now, I know it recognizes the command because if I input the statement with legacy format: if FAIL then 3 else 5 fi It automatically replaces the "fi" with the new form of "end if". So why doesn't it work? Thanks,
I am brand new to MAPLE. I have a large file full of equations which I want to put into a paper. Is there software, or a facility within MAPLE, to convert all these equations into WORD, or at least to TECH, without typing everything in again? Please respond with any help to Jerry Epstein
Hi, this is probably quite easy to do but quite a complicated thing to find out. Does anyone know how to plot more than one function on a graph so that for example, function f is plotted in the x-axis range from 0..10 and function g is plotted in the x-axis range from 10..100, both on the same graph. Thanks for your help.
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?

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

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);
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 on MapleNET or Download
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:
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
