HiIn connection with recent developments in the Physics package, we now have mathematical typesetting for all the inert functions of the mathematical language. Hey! This is within the Physics update available on the Maplesoft Physics: Research & Development webpage.

I think this is an interesting development that will concretely change the computational experience with these functions: it is not the same to compute with something you see displayed as %exp(x) instead of the same computation but flowing with it nicely displayed as an exponential function with the e in grey, reflecting that Maple understands this object as the exponential inert function, with known properties (all those of the active exp function), and so Maple can compute with the inert one taking these properties into account while not executing the function itself - and this is the essence of the inert function behaviour.

Introducing mathematical display, copy and paste for all these inert functions of the mathematical language concretely increases the mathematical expressiveness of the system, for teaching, working and also for presenting ideas.

Attached is a brief illustration.

This is just a question on terminology. The name "combine" implies pulling terms together. Yet, when applied to something like sin(x)^2 it has the effect of expanding it:

r:=sin(x)^2;combine(r);

Which seems counter-intutive to me. I tried first expand(r) but that did not expand it.

Fyi, in Mathematica the function to do the above is called

Sin[x]^2;TrigReduce[%]

1/2 (1 - Cos[2 x])

As Mathematica does not have a Combine[] function.

So, I am just wondering about the naming, that is all. I would never have thought first that a command called combine() will expand sin(x)^2.

Hi, all

I want to get some formular by the maple. I have some S domain transfer function, want to transform to the Z domain, but I don't know the way to realize it, is there any library function like "c2d" as in the Matlab? but "c2d" can not deal with the expression.

Thanks for replay to me!!!

Hi,

I'm preparing for GRE and i came across this question from 800score.com while reviewing concepts for probability.

In a deck of 52 standard playing cards, what is the probability that pulling a single card from the deck

will produce a black card?

Please...

I have bracket matching turned on but donot get the rectangular yellow box around matching brackets as shown in the attached picture. Can anyone help me how to turn this feature on for both input and output?

I have the following equation, I want to solve it for b keeping a and c fixed.

5*b^5+(60-5a)*b^4+(125+50c-80a)*b^3+(594c-445a-775)*b^2+(2324c-1005a-3270)*b+3000c-750a-3000=0.

How to solve it in maple?

I am using Maple 15 and every time I try to plot this equation it doesnt seem to want to plot. This is the code I keep trying to input:

plot(3*e^(-x)*x-e^(-x)-1.5*e^(-x)*(x^2)+e^(-x)*(x^2)*log(x),x=0..9,y=-1..0.6);

Every time I get "Plotting Error, empty plot"

The equation came from the original differential equation .5(d^2y/dx^2)+(dy/dx)+.5y(x)=ln(x)e^(-x)

Also When i try to plot this equation:

-.5*e^(-10*x)*sin(10*x)-.5*e^(-10*x)*cos(10*x)+(3/2)=300

Hello,

I've been trying to force maple to find a solution of this differential equation:

ode := -((D@@2)(y))(r)-2*y(r)/r+y(r) = (2-V(r))*u[0](r)

dsolve(ode, y(r));

gives

y(r) = r exp(-r) _C2 + (exp(r) + 2 exp(-r) Ei(1, -2 r) r) _C1 - 4 / / / |1 | | exp(-3 r) |- | | |2 | | \ \/ / 2 \ \

For a math class, we have to create a roller coaster. Part of the coaster consists of two banked curves. I've tried looking it up but Maple isn't very clear on how to create the. So, how do you create banked curves in Maple?

Today's SMBC strip by Zach Weinersmith is a silly math joke but it was pretty much begging for implementation.

So, here is a simple brute force Maple program to compute the Fouriest transform of an integer.

fouriest := proc(n::posint, ob::posint:=10) local b,f,cap,i,rdx,fc; ...

I have two differential equations describing a solar sail in 2D.

One is my radial direction and one is the tangential direction.

I have plotted r(t) and theta(t) but I want r(theta) so I have assigned my two differential equations and initial conditions, have my two plots for r and theta in terms of t and then I have used the following command to plot in polar coordinates:

I'm new in Maple and i've a project to do. I've to find at what time is 90% of the steady-state concentration of C achieved. And the eq is

z'=k(1/2-z)(1/3-z), where k=0.3.

So i had worked in Mathematica before and i know that it would look something like that in there:

eqn1 = 0 == k (1/2 - z[t]) (1/3 - z[t])

DSolve[Evaluate[{eqn1}], z[t]].

But i have no idea how to find this 90%. I hope that someone will...

Hello everybody,

I just realised Maple is allowed for my upcoming exam after New Year.

My plan is to have templates of the most common math problems, I might encounter for quick solutions.

Anyway, I have run into a problem with Laplace shifted data, particularly initial value problems. I have been searching for HOURS, and feel like I have look up everything on google, maplesoft and other sites without succes.

I hope some of you are able to help me. The exercise is:

I am working on a Maple project and it require me to pass a differential equation in a specific order like

x'=y & y'=x^2.(It is differentaiting w.r.t 't'(say))

However when I convert the equation into string it converts something as

diff(x(t),t)=y(t) & diff(y(t),t)=x(t)^2

Is there any way to stop maple from evaluating into maple/math format?

Is there any way to pass an equation without changing it's existing form?...
