I know these software packages were discussed a lot in the past, but I have not seen much input from the last couple years.
I have used Matlab for many years, but remember using Maple in University Physics courses many years ago. I'm interested in a software package for symbolic math to use...
Hi all, I am new to the Maplesoft software and have been experiencing trouble computing numerical integrals.
I defined a few mathematical functions in terms of a few variables like so:
I then used "subs" to input values to anything that isn't already a defined constant (like ##\hbar,\pi## and...
Hey there! I was trying to plot a ODE solution, but am not getting what I should be. It is actually plotting the orbit of Earth with Sun at the origin.
My equations
The (-0.00011847) is GM.
The Initial Conditions:
The plot I get:
Should not I be getting a elliptic/circular plot as the...
I have recently been doing some work that involves long, messy manipulations with lots of geometric series. A typical such series, which would only be one of a number of such terms in a formula, is:
$$
\sum_{t=h+1}^{T-h} \left(1-(1-\theta)^{T-t-h+1}\right)
\\
$$
It's not difficult to simplify...
hello dear,
I need to calculate the Weyl and Ricci scalars for a given metric. lets assume for a kerr metric. by using the grtensor-II package in maple i am not able to get the results. would anyone help me out. for ordinary metric like schwarzschild metric, However its not working for Kerr...
Is it possible to get Maple to show me step by step how to solve a complex contour integral?
f := (x,y,z,v) -> (x+I*x*cos(v)+I*y*sin(v))^(-2)
int(f(x,y,z,v),v=0..2*Pi) assuming(x,real,y,real,z,real,v,real)
But I would like to know how Maple solves this step by step. I tried using the tutor...
Hey so I'm working on a simulation to compute the multiplicity of two Einstein solids.. long story short I'm having a tough time plotting a function. To start, I defined the following:
Which, when simplified yields:
I named this simplified result K:

What I get is...
I used the following code and got the error:
Error, (in pdsolve) invalid input: `pdsolve/numeric` expects its 2nd argument, IBCs, to be of type {list, set}, but received IBC
the code is:
how to amend this error?
Btw, the second boundary condition v_x(1,t) should be approximated by the...
Which mathematical software(s) can you recommend for
1. As a substitute for a calculator (TI89): making basic graphs, regressions (linear, exponential), vectors, solving equations, showing graphs in 2d and 3d?
2. Writing an ebook with lot's of math.
I'm thinking Mathml or Mathtype might be...
1. Homework Statement
Using maple cw version, trying to write a state that will compute f=x/y^2 over several iterations.
y^2 is changing but x is dependent on a value input my user.
I don't really know how to write the loop?
I need the loop to run on an interval of different y values that I...
Hi All:
I am an electrical engineering undergrad. I would like to learn a math plotting software which would be helpful in visualizing topics in advanced calculus (my immediate need). It would also be helpful if the math plotting software was of some use in electrical engineering, but this is...
Hi,
I'm trying to solve this equation inside of Maple:
http://screencast.com/t/EeqzLhxS [Broken] for gamma(s)
I assign variables to each of the values like this:http://screencast.com/t/DBLS8BH6R [Broken]
When I try to solve I get this weird answer with a new _z variable...
Hi, I'm in my third year of a physics program, and lately I have really been struggling to figure out what program would be best for me to learn.
There are so many options out there. Octave, Scilab, Freemat, Matlab and then Maxima, Mathematica, Maple, etc.
So my understanding is that the...
The academics and the technicians of a university faculty are planning a paintball battle and the mathematicians are trying to predict their chances of winning with a continuous model. They are representing the numbers in the two teams at any time t as and respectively and have decided that the...
Hi, I have the next expression:
\frac{iw+3}{(iw-3)(iw+6)(iw+1)}
Now I want to find the real part of this expression via mathematica or maple, and for the love of god it doesn't work, what have I done wrong here?!
the codes and their errors are in the attachments...
Hi guys
I have 5 term which each term includes three function of time (autonomous system ), i want to obtain time derivative of each term as other terms for example if i define each term as a dimensionless variable , e.g. x , y , z , v , w , i want to know dx/dt = as a combination of x , y ...
Hi
I used plot digitizer software to pull data points off a picture of a graph and i need to fit a line to the points (and get an equation for the line). I know the data points fit to an s-curve from the picture. I'm thinking excel doesn't do this, or maybe I missed it?
I have access to maple...
Getting far enough along into math where I'm starting to wish I had something beyond my ti83..
Any recommendations in reguards to which program I should start with?
I've really no idea where to start, aside from googling "computational software"
What is the foremost program...
Basically I'm writing my MSc dissertation right now, and I've been doing a lot on primes
I've written all my code in MATLAB, but my supervisor told me today that MATLAB is crap for higher order arithmetic and the primes only go up to something like 10 digits long.
SO I'm kinda screwed...
I would like to draw plots by hand. Which means I can create the plot, label the axes, and then draw lines on it without having to write their equation. I can also control how the plot looks visually, such as color, scaling etc.
What program can I do this with? More specifically, can I do...
Hi everyone. I've been using basically a whole day on two trivial Mathematica issues, so I'm finally going online for help:
1. Is there any simple way to define the gradient as a new function as such? My try:
Clear["Global`*"]
f[u_] := x[u]*y[u]
gradf[u_] := D[f[u], {{x[u], y[u]}}]...

Hey guys,
I have this function:
f(r,z) = r*(1 + g(r,z))
The function g(r,z) is a modification of the student t-distribution in z, where the degrees of freedom depend continuously on r.
I would like to integrate this function f(r,z) from 0 to R with respect to r.
Unfortunately...
hi
i want to solve this equation
a/x=Cosh[b/x]
i set a=1 and b=5
and use NSolve code but mathematica say it can not solve it. but with maple i get real and imaginary parts.
1-is there another method to solve this equation numerically?
2-can this equation be solve for arbitrary a and b...
In a couple weeks, I'm going to be teaching a summer calculus class and I wanted to introduce my students to the mathematical software that can be used. However, where I teach they do not have maple or mathematica, so I have to use one of the open source programs (octave, maxima, scilab etc)...
Hi, I am new to this forum, so forgive me if this is a really obvious question.
I am a high school student interested in doing a project involving differential equations, and vector analysis (basically calc 1 - III, linear algebra, and a bit of differential equations). I will use this program...
Hi all. Ok, so I'm a mathematics major, but I'm only so far as my first linear algebra course right now. I have not had any need to use Maple or Mathematica or Mathlab or a calculator for that matter.
So, I'm curious WHEN I might have to start using these programs (what level math)...
