How can I solve this question the variational iteration method with maple.please help me!

Multiple Graphs in Maple

Jbone12115 — Sat, 19 May 2012 05:30:03 Z

I have an equation that is a function of two variables i.e Cp(beta,lambda). I have to plot several Cp curves on the same graph for a range of lambda=0..15 (x-axis). The 1st curve I want Cp@beta=0, 2nd curve Cp@beta=5, 3rdcurve Cp@beta=10 .... and so on

How can I do this without having to define a separate Cp equation for each beta value?

here is the code that shows the error message

are there anyone can help me a little bit and check it why?

Teaching Concepts with Maple

Robert Lopez — Mon, 14 May 2012 18:31:36 Z

Being easy to use is nice, but being easy to learn with is better. Maple’s ease-of-use paradigm, captured in the phrases “Clickable Calculus” and “Clickable Math” provides a syntax-free way to use Maple. The learning curve is flattened. But making Maple easy to use to use badly in the classroom helps neither student nor instructor.

In the mid to late ‘80s,...

Hello, I am new to maple and trying to teach myself as i go along. I am trying to plot a paramteric for a puck on a fristion less table that spins for differnt v_{o values. Here is my code: puckontable.mw}

Physics: Bead on a rotating hoop

koonduck — Thu, 10 May 2012 05:00:34 Z

Hello,

I am working on a physics problem that involves a bead on roating hoop. You need to use Lagrangians to solve this problem but this is not where i am strugling. My school expects us to use maple because it is the program the provide but none of the teachers know how to usem it (they use mathmatica) so they cant help us. We have the equation: θ"= [ω²*cos(θ)-(g/R)]sin(θ) and the initial cond. θ'(0)=0 and θ(0)=θ

How to make Maple understand a parameter which can assume only the values -1 and +1?

rickrsv — Thu, 10 May 2012 01:34:07 Z

Hi,

I am working with equations on Maple which depends on a parameter (epsilon), which can assume only the values +1 and -1 (I intent to replace this value only in the end of calculation). When, however, Maple computes the expressions, the result contains severals powers of epsilon, for instance epsilon^7 or epsilon^4. Since actually we have that epsilon^7=epsilon and epsilon^4=1, respectively, it would be very usefull to me if Maple

When maple does gauss elimination for matrice(student linalg). In "edit matrice" can i solve for x1,x2,x3..?

Four function, two interval, in one plot

Nimbus — Fri, 04 May 2012 15:43:24 Z

Hi! I have 4 function. I wanna plot two of them in x=-0.5..0 range; the other two in x=0..0.5 range. How can I display that four function in one plot? Thanks!

dsolve problem with plotting acceleration

Gbrandt — Thu, 03 May 2012 06:32:03 Z

so ill preface this by saying my knowledge of DE equations is rusty at best and my knowledge of maple even worse so this may be a stupid question. im trying to model the dynamics of a system and when i solve for the DE equation it's giving me an accleration of zero (plotting a blank graph) when it definitely shouldnt be. ive attached the worksheet.

Solving a Polynomial Function after i have expanded it

mag4112 — Fri, 27 Apr 2012 15:59:58 Z

I have to generate F(x) of a function with a degree of 5 who has zeros of x=2,x=1+3i,x=2-4i

After i put it into maple i use the command expand to give me the total function but afterwards i get this 144*i^4*x-25*i^2*x^3+x^5-288*i^4+118*i^2*x^2-8*x^4-188*i^2*x+25*x^3+104*i^2-38*x^2+28*x-8

i need to know what command can i use to get it to converts i^4 to 1 and i^2 to-1 that way i can truly simplify it.

How do I change the colour of certain words within a string?

Mikael71 — Thu, 26 Apr 2012 19:00:50 Z

I'm using the BoxPlot function and am trying to change the colour of two dates in the title="string" part, so they correspond with the colours of the two related box plots. Is there a way to do this?
