Hello everyone,

I am trying to figure out how to factor expressions like:

1+2*exp(x)+exp(2*x)

Simply trying factor does not work.

factor(1+2*exp(x)+exp(2*x)) => 1+2*exp(x)+exp(2*x)

Of course, I can force a substitution and make it work:

factor(subs(exp(2*x)=exp(x)^2,1+2*exp(x)+exp(2*x))) => (exp(x)+1)^2

In general however, I would like to not have to specify a substitution or even what is in the exponent!

Any help would be appreciated.

Thanks.

I'm trying to put together an analysis of a damped harmonic oscillator for a tutorial and I can't get the answer into the form I'd like. If you have a complex exponential, you can easily express it as a sum of a sin and cos using the convert function with the 'trig' option. If you have a term in the exponent that always evaluates to complex value because of the assumptions on your variables, however, it will always write the expression in terms of sinh and cosh. Is there any way to force Maple to put the solution in terms of sin and cos?

assume(A>=0);additionally(A::real);

Hi, I am trying to filter out solutions of 0 to 5 decimal places (i.e. 0.00000.....) from a loop. How do I do this?

 

Thank you.

Hello! First, please excuse me for my possible english mistakes (I'm french so...). Then, I need some help with Maple 11. As I wrote in the title I'm working on imaging. My aim is to create a lightsaber on a picture (as Photoshop do).

I am trying to add a point to an existing 2d plot, I understand how to plot functions and points but I can't seem to combine them into a single plot.  I am new to maple and still getting use to the functionality.  Any suggestions will be appreciated.

Friends sorry for the inconvenience ... it is this sheet:

I try this Explore(polarplot(1+a*cos(theta), theta = 0 .. 2*Pi)) but not work. I want to see how parameter a is changing the polarplot. this Explore(plot(1+a*cos(theta), theta = 0 .. 2*Pi, coords = polar)) is OK but not what I want. Thanks

Hello,

           I really need help creating a formula to get  the intersection  of 2 different sine waves with one single formula. I need to be able to vary the frequencies es and get data with one formula avoiding breaking down the process in different steps.

Does anybody know how to do this? I've tried for hours playing around with the basic sine wave forulae, attempting to make them interact but to no avail...

Dear my friends,

Recently I've written a program using Maple 13. During the program RUN following Attention appears:

 

-------------------------------------------------------------------------------------------------------------------------------------------

Parts of the expression are ambiguous. Please select one of the suggested meanings:

select a meaning for the expression:

function definition

remember table assignment

I have some expressions like the follwoing:

k := n*(phi+ln(-1/(-exp(phi)+exp(phi)*p-p)))/phi;

Moreover for some groups of expressions, I have a definition for mu and (sigma)^(2).

E.g.:

mu = n*p

(sigma)^(2) = n*p*(1-p)

 

Can I install Maple 14 and still use Maple 10 which is already installed?

In the list of how irrational, rational, and from small to large integers to sort.Can not calculate irrational. Can you help? Thanks

Hello I'm new here and I need some help from you guys

 

I try to create a simple maplets to find the solution for ODE problems (first order only) But I keep getting the error message that saying
