Hi,

Recently, I upgraded from Maple 13 to Maple 16.  I have been using Maple for 20 years --- Maple V Release 2 (1992) through Maple 16 (2012), and I participated in beta testing Maple V Release 4, which developed what we now call the Classic Interface.  The Classic Interface is amazing --- it was better than Mathematica in 1994 and it is still better than Maple's Standard Interface.  The Standard Interface is missing features that were...

1. a)given ∫(0..4)∫(√x..2) of sin(pi)*y^3 dydx, graph the region, R, in the xy plane.

b)Write double integral which reverses the order of integration and then evaluate.

2. Find centroid of cardioid of region enclosed by cardioid r=1-sin(theta)

3. a)Graph wedge cut from cylinder x^2+y^2=9, and by planes, z=-y, and z=0, and above the xy plane.

b)Write the integral which finds the volume of the wedge and evaluate it.

Will an older version of AEM (e.g., AEM 14) run with a newer version of Maple (e.g., Maple 16)?

Hi all,

Is there a quicker way to find all unknows from an expression?

Say I want a list contains ALL parameters. In this case, it would return

[w1,w2,mu,tau[2],tan[3],tan[4],eta[1],eta[2]]

Is there a way to do this?

Thanks!

As an intermeditae result I get from maple

It is obvious, that two fractions can be reduced by (1-t).

I could not reach this with simplify, solve, factor, expand, ...

Any idea?

In addition in the numerator (1-t)^2 is possible. How do I get this?

Thanks for any help !

Hello,

I have the following object:

t = ∫ (from 0 to e_0) [1 + (121/304)e²)]^1181/2299 (1 - e²)^-3/2 e^29/19 de

and I would like to plot t vs. e_0 on the interval 0 <= e_0 <= about 0.9.

So far, I have managed to get Maple to integrate the thing for any value I like of e_0 from 0 up to (but not including) 1. So, I now just need to get Maple...

Hi all,

I have a little problem.

I need to let maple solve: int( diff( u(x), x$2) * v(x), x=0..1), where u(x) and v(x) are arbitrary single variable real valued functions. Moreover Maple should consider v(0)=v(1)=0 while doing integration.

Maple is returning the integral as it is. I think some how I need to force maple to use integration by parts but do not know how?

I know maple knows: int( diff( u(x), x$2), x) = diff( u(x), x)

Hi all,

Here is the problem, I will try my best to describe it:

Firstly of all,

log(p[j,c]/(1-p[j,c]))=mu+tau[j]+eta[c];

In this system, the 'j' is a time varying parameter, and the...

the eight digits of your student Id number are used to individualise the questions. they are labelled a1a2a3a4a5a6a7a8a.. all non interger outputs should be to 3 decimal places. question 1_ depending of your own value of a8, write a program that performs the calculation below:

I purchased Maple 12 some years ago and I never used it. I want to download it to this new laptop and don't know how

Hi, I need help with graphing a certain logistics population model for an initial population size that is equal to 1.

dy/dt = k(1 - y/M)y  k=2 M(t)=10e^-t/5 +3(1-e^-t/5)

So far I've worked out the values to input, but I don't know how to write it in Maple.

I know all I have to replace is the M in the dy/dt equation with these 2 values.

M(0) = 10

M(t goes to infinity) = 3

Dear friends,

I have a basic question concerning Maple 15 (X86 64 LINUX). In fact it is so simple it is almost embarassing! Here it is.

When we do integration in a basic calculus class we learn that when integrating polynomials and series the constant that appears during the integration is usually taken to be zero, as polynomial and Laurent series terms will only produce powers and logs, but no constant. Of course the choice of constant does not influence definite integrals, as it cancels.

i want to solve this system of equation in analytic way in maple.

sys[Dx(t)+.01(.1x(t)+.1)^2*a+.01*.03*y(t)(1+x(t))*b+.02*.01*c*(z(t)+5)*(x(t)+1)=0,Dy(t)++.01*.03*y(t)(1+x(t))*a+.01*.09*y(t)^2+.01*.06*y(t)*(z(t)+5)c=0,Dz(t)+.02*.01*a*(z(t)+5)*(x(t)+1)++.01*.06*y(t)*(z(t)+5)*b+.01*.04*(z(t)+5)^2*c=0]

in this system a, b,c are costant

Hi there,

I am trying to graph some plots that show Gibb's Phenomenon. I assume that starting with a step function is a good idea.

I know how to plot a step function but I have no idea how to plot the curve that includes the overshoot?

Any help on how to add this to a step function plot would be appreciated greatly.

Thanks you

I consider a polynomial $P(x)$ such that their coefficients are in $\mathbb{Q}(u_1,\cdots,u_k)$ where $u_1,\cdots,u_k$ are complex parameters. I use in Maple the command $galois(p(x),x)$ and I obtain a fixed Galois group solution.  Fortunately, when I give explicit values (randomly chosen) to the $(u_i)_i$, I obtain always the previous group as Galois group. I think that Maple considers that the $(u_i)_i$ satisfy no algebraic equations, that is the $(u_i)_i$ are generic....
