MaplePrimes Questions

Hi, I want to know how to change the rectangular form to polar form, and how to manipulate the operation of them, for example the picture below. The angle of polar form contain radian and degree, how to represent them in Maple?Thank you.

 Can't copy from Maple worksheet and paste here in the Mapleprimes text editor. It's very cumbersome when one needs to detail technical examples. Is there a way to copy and paste?Thanks
Hello, I have been trying to complete a Maple homework assignment for my Caclulus class. I have been stuck on several problems for several days now and I was wondering if anybody could help me. Here are the questions on the assignment that I am stuck on. I know how to do these problems by hand, but I can't seem to figure out the roper commands to do them in Maple4. Given r(t)=(tsin(Pi(t)))i+(t)j+(tcos(Pi(t)))k over the interval [-2Pi, 2Pi}......    a. Find (dr/dt...
 I obtained a count of 7 with the command: stirling2(4,2) . How do I get a list of the 7 partitions? Thanks.

Hi,

I have been solving a system of non-linear ODE's for their steady states. This involves solving the rhs of the ODE's =0.

Hence I have been using "solve" in maple to solve a non-linear system.

Recently I have added more detail to the problem and now I am solving eight equations for eight variables and i've left overnight and maple still didnt find a solution. When sigma1=sigma2=0 below the problem is effectively 5-d and maple breezes through the calculation.

hi all..

i m solving a system of four coupled differential equations using bvp[midrich] technique on maple..

i have two questions..

1). is it possible to calculate the numerical data using bvp[midrich] instead of graphs?

2). there is a physical constant "A" in my second equation..can i compute its numerical values while fixing all other physical parameters of my equations...

If a, b and c are the roots of the equation x^3-x^2-x-1=0.
Find S=(a^2014-b^2014)/(a-b)+(b^2014-c^2014)/(b-c)+(c^2014-a^2014)/(c-a)

Today, I was working on a problem in the class which said:

if f(x)=ax^2+b, x<=1 and 1/x, x>1; then find the values of "a" and "b" such that f'(1) be defined. I checked it to be continuous at x=1 first and so I got a+b=1. Secondly, I wanted to get another equation, so I checked the differentiability of the function by the definition of derivation at x=1, so:

[> f := x-> piecewise(x <= 1, a*x^2+b, 1 < x, 1/x);
> limit((f(x)-f(1))/(x-1), x = 1, right);

I have a set E of linear equations in variables x[1],...,x[8] (which I created with X := Matrix(8,1,symbol=x)). I now call

 

> solve(E);

I get back something like

 

x[1] = x[2]-x[3], x[2] = x[2], x[3] = 5, ...

 

I would rather like to get

 

x[1] = t[1] - 5, x[2] = t[1], x[3] = 5, ...

 

back.

 

How to do this? I do want to use the solve function (not LinearSolve et.c.).

I'm supposed to do the following. I tried to ask my teacher how I could go about doing it and she told me to just figure it out. I am supposed to find the linear and quadratic approximations to the function f at x=a. Then, I'm supposed to sketch the graph of the function and its lienar and quadratic approximations.

The linear approximation is:

P1(x)= f(a) + fprime(a)*(x-a)

The quadratic approximation is:

P2(x)= f(a) + fprime(a...

I have that problem that I am trying to solve the following equation explicit:

TY = RootOf(6.750969101*10^26*_Z*1000^(9/59)*800^(41/59)-1.015701668*10^27*1000^(50/59)-1.189275761*10^27*800^(50/59)+1.103397224*10^26*_Z*1000^(32/59)*800^(18/59)-7.457053114*10^23*3^(1/5)*1000^(41/59)*800^(50/59)*_Z^(4/5)*sqrt(12500)*4^(19/20)*(800^(9/59)+1000^(9/59))^(1/50)*(702.222720*1000^(9/59)+976.508160*800^(9/59))^(4/5)-7.457053114*10^23*3^(1/5)*1000^(50/59)*800^(41/59)*_Z^(4/5)*sqrt(12500...

Can maple in any way simplify this any further?

-(1/4)*m*omega*sin((1/2)*omega*T)*(2*cos((1/2)*omega*T)^2*xa^2+2*cos((1/2)*omega*T)^2*xb^2-xa^2-2*xa*xb-xb^2)/((cos((1/2)*omega*T)^2-1)*cos((1/2)*omega*T))

I've tried simplify, radnormal, combine but am wondering why maple does not convert for example the denominator in sin(omega*T) 

How do enter and use the notation of a step function (u(t-3)-u(t-4) in maple to use in calculations? thanks

Hi,

I wondered if you would be able to help.

I've set up a for-loop and while-loop that substitutes values of j and k into a given function

I want to get the answer for every right for example right[1], right[2]..but this code give the answer for right[1]nd right[6] only..

 

 P := array([[1, 4], [2, 3], [3, 2], [4, 1], [6, 5], [6, 1], [6, 2], [5, 3]]);

j := 1; k := j+2; Fold := 0; Fnew := 1; counter := 0;
