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...

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:

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.

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?
