When using the command "for", the results are placed in a column,such as if we input
for i from 1 to 3 do  i end do, the results are showed as

1

2

3.

This style is not convient to use for following computation. So how to put all results into a list or set ?

Give a polynomial a*x+b,We can use the command "coeff" to get a coefficient of x. Unfortunately the command does not work for functional work. I have a comlicated functional expression, and want to get the coefficients of some given basical term. How can I do to get the coefficients?

Hello,experts! I meet a strange problem. That is to solve a equation but use other variable,namely solve(2*x=3,y).I hope that the returned result of command "solve" is y=0. How can I to do to realize it?

I meet a problem. When I use command "if" in command "for", there is nothing.I don't know reason. Can anyone tell me the reason?

Hi i'm new to maple.

Is there a way to remove commas from a list?

I was able to remove the list from its brackets []
but i was wondering if I'm able to remove the commas also?

Hi,

My question is fairly straight-forward, I hope someone has an equally straight-forward solution. I would like to be able to illustrate the convergence of the distribution on the mean of i.i.d random variables to the normal distribution. For example, I'd like to visualize (by way of a histogram plot) that as n increases arbitrarily, the mean of n i.i.d. exponential random variables with mean 10 converges to a normal distribution.

Thanks!

I am considering bu;ying an imac and want to run maple 15. I have a personal library, called Mylib. I use on my windows platform. I use an ini file that maple 15 reads when it first opens. In this file I modify libname with the statement,

> libname:=libname,"c:\Mylib";

My question is how do I do this on the mac version of maple?

I'm looking for a simple way, e.g. a function, to convert a system of symbolic equations in its matrix form.

Like

(a+1)x - by + cz = j

2x  + (sqrt(d)+e)y - fz = k

(g-h²+1)x - iy - 4z = l

shall be transferred to matrix / vector form

A . x = b

where A i the matrix of the coefficients, x i the vector of the variables (x,y,z), and b is the right-hand-side vector (j,k,l).

The number of equations...

Hello,

I'm new at maple and I was wondering if someone could help me. I've got a function with 3 variables:

v1'=(v1*sqrt((1+u)^2-4*u*cos(b)^2))/(1+u)

Can you plot this function? Or do I have to give one or two variables a value and plot the function 3 different times with just one variable?

Thanks

I'm Trying to calculate the Determinant of a 3 x 3 Matrix with symbolic entries with maple 15. But the Determinat function gives a wrong result. From the C+A-1 expression it uses only the C and ignores the rest.

When I calculate it "manually" the result is correct.

Here is what I'm doing:

The Maple file is attached to this question.

Please, consider this example:

I wonder why the match function returns TRUE and expressions that depend on the main variable x. I hope that someone can give me an explanation.

Hi,

I have a pretty simple problem. Given the following set of responses to a "yes (y)/no (n)" question, create a pie chart and a bar chart.

y, y, n, n, n, y, y, n, n, n, y, y 

I would like solution that does not involve coding the data, say y = 1 and n = 0. I am aware of the BarChart and ColumnChart commands in the Statistics package, but I can't seem to get them to work with nonnumeric data. Is there an easy way to do this?

The folks at Grand Valley State University have posted a nice set of Maple tutorial videos on YouTube.  The videos have been designed for students taking 200-level math courses, but they are certainly suitable for anyone who is either new to Maple, or looking for a refresher.

Enjoy!

I want to plot the data with some error bars. I have tried the errorbar( ) function but it doesn't work. May I know what is the problem ?

I don't know why maple can't solve this PDE
