Is there any way to convert the output of ToInert to a graph/tree representation?
ToInert's output type is a function and I've tried converting it to an expression  first but didn’t succeed. I've also looked for functions in the GraphTheory package that could help in this process but didn’t manage to find anything useful.
Thank you.

Attached is my sheet. Please have a look.  my_scrach_Sheet.mw

Have a look at the last command of the sheet.

I am trying to extract integrals from the equaions(eq10_1, for example) using 'op', but it isn't working as expected, is it a bug or I am doing something wrong?

Second question: 

I am not been able to do sorting for all these equations, any suggestions?

I have been trying to find a solution to the following equation for ages! 

Vt:=(a*t)+((1/(2*Pi))*((b*cos(2*Pi*t))-(c*sin(2*Pi*t))-b)-295);

I need to find what t converges to, I have solved the equation using a different method and I know the answer is around 0.787 but I need to find the result using the Newton Raphson method, or another iterative method. I am not allowed to use dsolve. or the Newton command.

Hello, 

I have plotted a function f(e) vs. e (see code and figure). However, the graph looks jagged and nasty. I tried increasing the numpoint value but this doesn't seem to work (even at 50,000!). I'm fairly new to Maple and so I don't know any other commands/ tricks to help myself. 

Does anyone know how I smooth this plot?

Thanks.

Code: 

> f := (1+(73/24)*e^2+(37/96)*e^4)/(1-e^2)^(7/2);

Hi!

In the program below, all solutions are found for the equation S.R=T subject to 

the constraints given by eq1 and eq2. I've tried it for a 

few different choices of T and there's usually 80+ solutions.

I want to try more complicated choices of T (for example,

I want the matrix T to have every entry a distinct prime number). 

But then the program crashes. I assume the equations get complicated

or there...

Sorry if this is a bit vague...

I have a list.  I am applying a loop with a condition.  When the condition is met it stops (of course) but how do I get the condition to continue testing against the rest of the list without incrementing the next loop value?

T := Typesetting[delayDotProduct](sqrt(2/3), Matrix(3, 3, {(1, 1) = cos(omega*t), (1, 2) = cos(omega*t-(2/3)*Pi), (1, 3) = cos(omega*t+(2/3)*Pi), (2, 1) = -sin(omega*t), (2, 2) = -sin(omega*t-(2/3)*Pi), (2, 3) = -sin(omega*t+(2/3)*Pi), (3, 1) = 1/sqrt(2), (3, 2...

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:
question.mw

one angle is 45 degree and one side is 4 find the other remaining two angles and sides, how?

part of my codes are:

func[1] := (1/2)*(c+s)*x[1]+s*x[3]+(s-c)*x[1]*x[2];
func[2] := (1/2)*(c-s)*x[1]+s*x[3]+(s+c)*x[1]*x[2];
func[3] := -b*x[2]-x[1]^2; 

They are just three ODE , how to fix the error?Where is the so-called recursive assignment...?

The program works well when:

"func[1] := x[2] + (x[1]^2 - x[1]*x[3]);

func[2] := - x[1] +  (x[2]^2 + x[1]*x[4]) + x[2]^3;

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].

In my complex root finding problem it is essential to obtain complex roots in each period of the function. to do this i have write the following code with functional periods but it doesnt work. would you please tell me why? and how can i correct the code?

A curve has the equation y=f(x).

Find the eqn of the normal to the curve at the point x=x0 in the form y=g(x, x0) and write a procedure to plot curve y=f(x) with its normal at any point on the curve.

Animate the plot so that the normal is seen sliding along the curve.
