I use gnuplot to generate graphs in C++.Now we all know that in C++,we  just pass a text file to gnuplot,tell it to plot the text file.

Now,in Maple I want to do the similar thing,like this:

Suppose I have some single variable function/procedure,say of x

then I can write a loop say,

for 0 to 100 by 0.01 do

x,f(x)

od;

With this I can see the output.Now if I want the plot of f(x) vs x,then how can I say it to Maple?

I have a system of three differential equations with three unknowns, say f(t), g(t) and h(t).

My problem is that the system involves also f(invh(g(t))), g(invh(g(t))) and f(invg(h(t))), where invh is the inverse of h and invg is the inverse of g.

How can I instruct Maple to deal with these inverse functions?

I came across this problem while helping another user find the maxima of an expression for 
various values of a parameter here:

http://www.mapleprimes.com/questions/124104-Maximum-Points--Of-Function-With-More

For various values of ga, it was required to find the maxima in a range of 0<delta<2. 
Plots of the expression indicate that one such maxima exists for each value of the parameter.

My approach was to find the zeros of the first...

The Units package includes various units that are called ton/metric ton/tonne/short tons but not long tons (LT). A long ton is equal to 2240 pounds of weight and is part of the imperial system, so it is also know as the "imperial ton" or the "weight ton".

This unit (the long ton) is used extensively in naval architecture and ocean engineering. I would hope that you consider adding it into the next update of the Units package.

Or perhaps, it would...

I really need a result to the integration below but Maple 13 just won't return one. Could you please help me or advise me as to what might be wrong or what I might try ? I'm integrating on the real line in x but even when I alter the limits of integration maple just returns the integrand.

s1:= int((1/8)*sqrt(2)*exp((1/2)*k^2*cos(x)^2/sigma^2)*exp(-(1/2)*k^2/sigma^2...

I have a system equations like { a + b = 1, c = a + b +1, d = a + c}

and the sovle function which give me then answer like { a = -2+d, b = -d+3, c = 2, d = d}

I just care about the information in form (name = numeric) like { c = 2 }

and i want the "core" equations which give me that information like { a +b = 1, c = a +b +1 } => {c = 2}

how i can i get the "core" equations of that.

The integrals are

v1:=int((1/(2*Pi) + Q* cos(k*phi))^2/ (1+ beta^2*((1/(2*Pi)) + Q* cos(k*phi) )^2),phi=-Pi..Pi);

v2:=int((1/(2*Pi) + Q* cos(k*phi))^2*cos(k*phi)/ (1+ beta^2*((1/(2*Pi)) + Q* cos(k*phi) )^2),phi=-Pi..Pi);

v3:=int((1/(2*Pi) + Q* cos(k*phi))^3*cos(k*phi)/ ((1+ beta^2*((1/(2*Pi)) + Q* cos(k*phi) )^2))^2,phi=-Pi..Pi);

v4 := int(exp((-1/2)*((psi-theta-k*sin(theta-phi))/sigma)^2),phi = - Pi ..Pi);

In 2010-2011, I persuaded tens of thousands of Russian and Ukrainian students and students in that Maple - a very useful thing.
Testimonials - the number of visits and thanks.
So I decided to resurrect some of my old sites.
Not just for history!

I am having a strange experience with the arrow command.   In the attached worksheet, one can see that plot structures h, i & j and l, m & n are both doing the essentially the same thing:   A vertical line is to be drawn and arrows pointing up and down from the two endpoints are to be added.  The arrows are all of the...

I need help in finding the maximum point of each curve (please see maple file link attached), or if possible display each maximum point (under different "ga") on the 3Dplot

Your help is appreciated

Hello, I'm new to Maple.
when I write:

solve({Wa=Ve,-4*Vd+4*Ve=-4*Wa+4*Wb,12*Vc-24*Vd+12*Ve=12*Wa-24*Wb+12*Wc},{Wc});

Maple gives me no output.
Can somebody help me, what I'm doing wrong? (Maple 9.5)
Thank you for your help! 

 Hello, everyone,
I have two problems in my worksheet.
First, when I specified the value of "s1" for a smaller number, for example 1e-5 or 1e-6, the imaginary part of "an" tends to infinity or -infinity, however, it should be finite.
Second, the value of "an" is instable when specific value of "s1" is choosen. For example, in the attached worksheet, s1=1.9e-4, the value of "an" will be changed when you click "!!!" button several times(that means execute the entire worksheet).

My contour of integration is a semi circle whose diameter rests on the imaginary axis from -ri to ri.  The arc of radius r is on the positive real axis going from -ri to ri.  On the curve I want to have directional arrows indicating that I am traversing this contour in the positive direction.  How do I create this figure in MAPLE?
