Hi there,

Can you please help me to plot delay logistic equation for

dy/dt=y(t)*(1-y(t-1))
y(0)=1/2  ALSO  y(1)=1/2
where t=0..100

Thanks for help

There is some advice how to solve a cubic trigonometrically  here, but nothing presentable seems to appear out of it. Could someone please demonstrate how to do that with maple for a general (monic) cubic. Thanks.

I realized the other day that I had not mentioned the Threads:-Add, Threads:-Map, Threads:-Mul and Threads:-Seq functions.  These are parallel implementations of the standard Maple functions, add, map, mul and seq.  They expect the sam

`<,>`(`<|>`(x+1, x, x, `...`, x), `<|>`(x, x+2, x, `...`, x), `<|>`(x, x, x+3, `...`, x), `<|>`(x, x, x, `...`, x+n))

but  ellipse between rows can't be added like the same way?

Matrix(5, 5, {(1, 1) = x+1, (1, 2) = x, (1, 3) = x, (1, 4) = `...`, (1, 5) = x, (2, 1) = x, (2, 2) = x+2, (2, 3) = x, (2, 4) = `...`, (2, 5) = x, (3, 1) = x, (3, 2) = x, (3, 3) = x+3, (3, 4) = `...`, (3, 5) = x, (4, 1) = `:`, (4, 2) = `:`, (4, 3) = `...`, (4, 4) = `...`, (4, 5) = `:`, (5, 1) = x, (5, 2) = x, (5, 3) = x, (5, 4) = `...`, (5, 5) = x+n})

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
