Hi everyone, I have a problem with the plot of a function I'm trying to use. The function is quite complicated and when I try to plot it between k=0..100 for example, it will only show the half of the points. What is the problem?
Here is the function Im talking about:

Hi all,

I have a problem with 'Rank' when trying to find the rank of a matrix.

For some purpose, I have to load both with(LinearAlgebra) and with(Statistics) packages.

Without using Statistics[Tally], (not loading the Statistics package), the Rank works fine.

With the Statistics package, Rank sometimes gives an error, saying,

Error, (in Statistics:-Rank) expected 1-dimensional Array, but .....

I now fix this by using LinearAlgebra[Rank].

How can I simplify the following expression

sin(x+pi/4)+cos(x+pi/3)

to the following form

A*sin(x+B) or A*cos(x+B)

where A and B are calculated constant

How do I convert the following trigonometric expression?

->

I want to simplify the following trigonometric expression

sin(x)*1/2+cos(x)*sqrt(3)/2

to

sin(x+pi/3)

how can I complete this procedure?

I need help solving the following:

Plot y=x^2 and its tangent line at x=1, y=2x-1, on the same x-y plane over the following intervals:

a [0,2]

b [0.9,1.1]

c [0.99,1.01]

d Observation

Any help would be appreciated.

I'm filling an array of functions like this:

Hi

I am trying to do a phase plot of an autonomous system using DEplot command. However, no phase plot appears. Could you tell me what am I doing wrong? The same code worked for my professor in class, but it's not working for me. I am using Maple 16. The code is posted below.

> with DEtools

> sys := diff(x(t), t) = y(t), diff(y(t), t) = x(t)*(1-x(t)*x(t))+y(t);

> DEplot([sys], [x(t), y(t)], t = 0 .. 0.1e-8, x = -3 .. 3, y = -3 .. 3, color = black)

  Hey,

 I am using maple to do some numerics (bound to use it instead of mathematica because of university guidelines) and my problem is that as the plotting options of maple are a bit unsatisfactory I need to export my data. This has worked fine so far using the writedata-command while I was working on normal (10 digit) precision. Now however I need to increase the precision and to my dismay writedata just cuts everything after the normal 10 digits away and...

with(ScientificConstants):

GetElement(Ra,atomicweight);

Hi!

I think I have quite simple problem, I can´t solve.

I have the following fraction:

and want to show it this way:

Multiplying the first fraction with (-1)/(-1) doesn´t work as expected.

Bonjour,

Qui peut m'éxpliquer l'algorithme de division d'un polynôme P(X,Y) sur un polynôme Q(x,y) ?

Avec mes plus vifs remmerciements,
Raymond Gérard.

If Z is N(0,1) find

a) P(0<=Z<=.87)

I understand how to get to 0-0/1<=Z-0/1<=.87-0/1

which ends up being OI(.87), but am not sure how to get this to calculate. Plus I ant use proper functions here becuase I dont have the pallette, but OI is an O with the I through it... Φ(.87) I beleive....

I dont know how to have Maple calculate ths to give me the correct normal distribution value.

I have a Matrix 'A' in maple with symbolic entries and I need to use that Matrix in matlab M file. The symbols with in 'A' are already initialized in M file.

How is this possible?

For Matrices 'A' of small dimension, I can use the codegeneration package to convert 'A' to Matlab Matrix and then copy paste.

But for matrices of 1000x1000, lets say, does not seem as a option.
