Whenever I try and solve the equation x^4 + 6*x^3 + 3*x^2 + 6 = 0, I get crazy answers :(

Anyone know how to do it?

Thanks for any replies (Note: I am very new to MAPLE so please use basic language)

Hi

I'de like to see the solutions of the system of equations :

how can i form a taylor series of:

F(x,y)

here F(x,y) = [f1(x,y); f2(x,y)]

about a point X = [alpha, beta] such that F(alpha, beta) = 0

this tell me,some notation systems are effient,and some are not...

I want to do a very high-dimensional sum.

Particularly, this sum, where each of those indices can be either 0 or 1:

http://scienide2.uwaterloo.ca/~ndattani/temp/template.pdf

I started doing something like:

sum(sum(sum(sum(R,a[0]=0..1),b[0]=0..1),a[1]=0..1]),b[1]=0..1)

But it seems that there must be a better way (one in which I can genarlize to n dimersions). Is such a thing possible in maple ??

can Maple do the termwise integration?I'm not familiar with that,

The part on the right of equal sign is what I copied from arctan(z),of course the equation doesn't exist,and that is what I would edit manual,

but the equal sign is strange,which to choose ? though that is unrelated to the overall situation...

anyone can tell me something about termwise integration in maple?

Hello,

Whenever I integrate ((sinx)^4)*((cosx)^3), MAPLE gives ((sinx)^4)*((cosx)^3)x as an answer, effectively just sticking an x on the end of it.

Surely this is incorrect? How do I get it to integrate properly?

I am very new to MAPLE by the way so please speak in basic language!

Thank you to anyone who replies

c := proc (n) options operator, arrow; z^n/factorial(n) end proc

limit(c(n)^(1/n), n = infinity),

limit(c(n)^(1/n), n = 6)

eval(limit((z^n/factorial(n))^(1/n), n = 6))=(1/60)*12^(2/3)*5^(5/6)*(z^6)^(1/6)
 

evalf(limit((z^n/factorial(n))^(1/n), n = 6))=.3340241884*(z^6)^(1/6)
 

how to get z but (z^6)^(1/6)

how to input suspension points,and that in a matrix or determinant……

I want to solve a system of 2 equations and 2 variables with solve functions.But,I receive invalid argument error.the problem is following:

 R11 := {(200*(-0.8e-1*t+0.8000000000e-1))/p^2-(120*(t-0.3999999999e-1*t^2+0.3010e-1*t^2.5))/p^3-25.0000*t^1.5/p^3-(46.67*(-5.760000000+6*t-.24*t^2))/p^3-(100*(0.8000000000e-1+0.50e-1*t^1.5))/p^3 = 0}

Hi,

I,m totally new to maple and am trying this as a tool to help me with my calculus class. I'm trying to figure out how to create a plot from a table of x and y values, but I'm not having a lot of luck.

The goal would be to plot a Riemann sum once I have created the plot. If anybody can point me in the right direction that would be great.

Thanks,

Mark

method 1:

p := [`$`([n, 1], n = 2 and n = 3 and n = 5 and n = 7)]

plot(l, x = 0 .. 15, style = point, symbol = circle)

how to make method 1 right,I know if n=1..7,that's right,but n should be prime numbers.

Is there prime plot?

question2:

plot(piecewise(x = 2, 1), x = -2 .. 6) or plot(piecewise(x = 2 and x=3 and x=5 and x=7, 1), x = -2 .. 6)

why this is not right,I can't see the point (2,1)...(3,1),(5,1),(7,1)

question3:

add plot label directly,p1 := plot(piecewise(x< 2, 1), x = -2 .. 6)

I use eliminate to get a relation of two independent variables,and then I want to use plot to draw a picture of the two independene variable,such as

eliminate({L[A]+L[DD], S[A]+S[DD]}, kk)

and I got the relationship of kk&w,I want to draw the relationship,maybe plot can not do it ,what others I can do?

thank you

On and off over the last few months I've been meaning to learn about computing a center manifold approximation and normal form of a dynamic system of three differential equations.

My main reading: Stephen Wiggins, Introduction to Applied Nonlinear Dynamical Systems and Chaos, Second Edition, Springer, 2003.

I want to apply the technique to a system I derived from an optimal control problem. As a first step, I decided to reproduce the steps for the following system, for which the solution has been published.

Below is the latest version of the code to draw iso-chrone lines and a salvo of arrows onto the phase diagram of a two-dimensional system of ordinary differential equations.

I have greatly benefited from inputs by Robert Israel (who wrote the first incarnation of the procedure), Joe Riel, and pagan. A big thankyou!

The procedure is sufficiently developed for my current purpose, so I don't plan to modify it much in the near future.

Tested on Maple 13/ Classic. The last plot combines the isochrones and the salvo.
