   Maplesoft aims to promote innovation in science, technology, engineering and math (STEM) in high school students by partnering with various organizations, and sponsoring initiatives in education, research and innovation. Every year, Maplesoft commits time, funds and people to enhance the quality of math-based learning and discovery and to encourage high school students to strengthen their math skills.

   One such organization we partner with is The Perimeter Institute, a leading centre for scientific research, training and educational outreach in foundational theoretical physics.  Maplesoft currently serves as its Educational Outreach Champion, supporting various initiatives that promote math learning and exploration. Perhaps the most popular of its student outreach program is the annual International Summer School for Young Physicists (ISSYP), a two-week camp that brings together 40 exceptional students from high schools across the globe.  Each year students receive a complimentary copy of Maple, and use the product to practice and strengthen their math skills.  The ISSYP program also uses Möbius, the comprehensive online STEM courseware platform from Maplesoft, to offer preparatory course materials to students.  Completing lessons in Möbius aid in making the summer program a more productive and dynamic experience for the students.

   Who Wants to Be a Mathematician is a competition organized by the American Mathematical Society (AMS) for high school students in North America. Maplesoft has been a sponsor of the contest for many years.  Maple T.A., the testing and assessment tool by Maplesoft, is used to administer the tests online, saving significant time and money for the organizers. When Maplesoft first introduced Maple T.A. to the contest, taking the competition from pen-and-paper tests to online tests, the number of contestants doubled, with about 2000 students participating in the contest. Maplesoft also donates prizes to the games in order to promote the use and love of math by high school students.  This year will be first time the competition moves international. Six students in the UK took the Round 2 qualifying test, with the use of Maple T.A., and qualified for the live, on-stage finals of the UK edition of the competition that took place at the 2017 Maths Fest in London. Maplesoft is also supporting the spread of the WWTBAM contest to Canada in 2017.

Maplesoft also sponsors two outreach initiatives in Texas A&M University.  The Summer Educational Enrichment (SEE) Math Program is a summer workshop attended by gifted middle school students. Students spend two weeks exploring ideas such as algebra, geometry, graph theory, and topology.  The University also conducts the Integral Bee every year, a math based contest for high school students.

In addition to the above key projects, throughout the year Maplesoft also sponsors and is associated with a number of other competitions, conferences, and educational initiatives. A few of these are listed below.

  • The Connecticut Science & Engineering Fair is a yearly, statewide science and engineering fair open to all 7th through 12th grade students.  An important objective of their program is to attract young people to careers in science and engineering while developing skills essential to critical thinking.
  • FIRST Robotics Competition is a high school robotics competition. Each year, teams of high school students and mentors work during a six-week period to build game-playing robots that weigh up to 120 pounds.

 

FIRSTRobotics Competition

  • ScienceExpo Conference is a student-run event that engages students with STEM-related opportunities and workshops
  • SWATposium is an annual robotics conference that brings together nearly 40 First Robotic Competition teams from both Canada and the United States for a day of guest speakers, workshops and social activities.

        

SWATposium

  • FIRST LEGO League gives elementary and middle school students and their adult coaches the opportunity to work and create together to solve a common problem.

   Maplesoft’s objective of these sponsorships is to support those who inspire and channel young minds to be STEM focussed. By engaging them in exciting contests and programs the hope is that they build science, engineering, and technology skills at a young age and grow to be innovators and technology leaders of tomorrow.

The problem I am trying to solve requires a significant amount of computation time. I am unaware if a solution to the problem exists. If a solution does exist, I only need one solution, not the set of every possible solution. Is there a way to restrict the solve function such that when (if) one solution is found, the computation halts and the solution is outputted?

I have 5 equations mentioned as below,

a[0]=L+(2*beta*mu)/(3*alpha*omega^2);

a[1]=sqrt((4*mu)/(3*alpha*omega^2));

a[2]=(2*beta*mu)/(9*alpha*omega^2);

a[3]=sqrt(mu^3/(432*alpha*omega^2));

omega[s]=omega-(mu^2/16*omega)-((2*beta^2mu)/(9*alpha*omega));

 

Left-hand parameters i.e. a[0],a[1],a[2],a[3], omega[s] are known , and each equation on right hand contain unkonowns i.e alpha, mu, beta, omega.

I want expression for unknowns in terms of knowns.

What can i do in this case? I,m traying solve a system of non linear equation like this, i want to know Rs and Rsh:


Hello,

 

I want to determine the unknown out of the equation, and I do not know why I have such an error.                             

Error, (in MTM:-solve) {5*x-3 = 19} is not valid equation or expression

Why function Solve doesn't work?

I will try to explain with an example, lets say i have to solve 2 equations with 2 unknowns

P := solve({3*y+x, 2*x+3+y})
solve({3*y+x, 2*x+3+y})

I would then like to do P[1] and P[2] to get the values, but instead it gives me "x=-9/5" which make me unable to use it for things like

P[1] + P[2]

Hope you all understand, and thanks for taking your time to read my problem 

i have these commands:

restart;
with(plots);
with(VectorCalculus);
with(LinearAlgebra);
f := A-B+x^y/y;

g := x^y-y;
Solve({f = 0, g = 0}, {x, y});
              / /                     y    \         \
              | | y                  x     |         |
         Solve|< x  - y = 0, A - B + -- = 0 >, {x, y}|
              | |                    y     |         |
              \ \                          /         /

restart; with(plots); with(VectorCalculus); with(LinearAlgebra); f := A-B+x^y/y;  g := x^y-y; Solve({f = 0, g = 0}, {x, y});

 

but I can't get it to actually solve the equations. what do I do  ?

Hello,

I've just started to use Maple 16, and I can't seem to get a neat result, when I use the solve function to solve 4 equations with 4 unknown constants.

I've posted my calculations.

 

How can I get a simpler result? I found a simplification command, but that didn't help

I solved this (aq1) equation and got a set of answers, but when I want to solve another equation (aq) that is like (aq1)  it took a long time and I stopped progressing.

How can I solve (aq) ?

Here is one that the students generated which caused confusion. 

a := 0.76;
eq1 := 2*cot(a*sqrt(2*E)) = (2*E-5.4)/(sqrt(E*(5.4-E));
solve(eq1, E)

And the results are: 0., 4.411954070, 2.423743792

The problem is with the second answer because it does not exist. If we plot the LHS and the RHS of eq1 vs E where E=0..5.4

plot([2*cot(0.76*sqrt(2*E)), (2*E-5.4)/sqrt(E*(5.4-E))], E=0..5.4, -3..3)

And it gets more interesting, if we calculate:

solve(evalf(eq1), E)

The answers are: 0., 2.423743793, 14.33807304+27.39159712*I

where the 3rd answer is again incorrect.

Finally, if a = 0.8 or larger, the incorrect answers disappear. 

Note - fsolve does handle this problem correctly. And despite my attempts to remind them to use fsolve, they see the solve command as the universal truth. Apparently this will be another teaching moment for next year.

So any thoughts about why this happens and why there is a difference in the outcomes between 0.76 and 0.8 for the value of a?

Can somebody execute this code on a powerful comp and report the result in MaplePrimes? That would be kind of her/him.

I'm trying to solve this integral, but maple does not show any result.

f := GAMMA(phi)*y^(mu*phi-1)*(1-y)^((1-mu)*phi-1)/(GAMMA(mu*phi)*GAMMA((1-mu)*phi))
int(log(1-y)*f, y = 0 .. 1) assuming phi >0 and 0<mu<1

What is the problem? Is there any way to solve this integral?
