how to solve

for a

i tried

and got

HI

Can anyone help me.

I would like to use the combin package using Maple 12. The question is how can I generate the letters of the alphbet (26 letters) choosing only 3 combinations which must include the letter "A" 

any help would be appreciated

Please explain details of the fmt string in the mapleta function numfmt.  The help page only says

Returns the value of x, formatted according to the template fmt.

 For example,

 numfmt("#.00", 20.9)

Hi!

Problem: How can I prevent Maple from checking against the simplification table?

Eg.

I enter

f := 5 y z x + 3 x^2;

and 5zyx + 3x^2 is returned.

Then I enter

g := 3 x^2 + 5 x y z;

and again 5zyx + 3 x^2 is returned, but not wanted, because I wanted to have a different (visual) representation of the polynomial.

How can I prevent this? Or how can I delete the first representation from the simplification...

Dear Sir / Madam,

Would you recommend me how to isolate the real and imaginary part and simplify the equation A? Maple cannot evaluate this equation to numeric value...

A := evalf(sqrt((Re(B))^2 + (Im(B))^2));
A := evalf(abs(B));

are not working.

I have attached my equation function.txt

I will include the work i did, also near the end of the worksheet, there are word descriptions of the questions i did.

Im stuck on the last 3 questions: question 14, 15 and 16. I cant seem to find the values i need for my Ce^-kx

I tried diff it but my syntax is preventing me from going farther.

All help will be appreciated! i will include the original lab for more clarification!

f(x)=(sin@@3)(0.5143600172e-2+1.000000039*arcsin(arcsin(sin(sin(-0.1543083839e-1+.9999999610*RootOf((sin@@3)(_Z)-(sin@@3)(0.5143619410e-2+1.000000000*RootOf(-(sin@@3)(_Z)+x))))))))

i want to find inverse of this funtion i am getting nothing

>s := solve(w = f(x), x)

    s:=

i am getting like above.

i want to find inverse of above function plz give me reply to me.

I finished this lab for my Differental equations class today. The computer I was using is not linked to a printer. I saved it and went to open it on a differnet compter and I got an error saying there are problems with the loading process.  I tried reopening it on the computer I started with and I get the same error

The lab has three parts. The first two parts were part of the the professors instructions and introduction. Those parts load up. The third part is...

With f := i->`if`(i = 0, 1, alpha), I'd like to evaluate expression A below entirely symbolically, i.e. with l=1..3 being replaced with l=1..h in

sum('sum(sum(f(i)*f(i+j), i = 0 .. l-1), j = 1 .. h-l)', l = 1 .. 3); subs(alpha = .3, h = 3, %);#A

but using  A with l= 1 .. h provides a different number, the one one obtains with

sum(sum(sum(f(i)*f(i+j), i = 0 .. l-1), j = 1 .. h-l), l = 1 .. h); subs(alpha = .3, h = 3, %); #B

Expressions...

Hi,

I'm new to Maple; well, I've been 'away' from Maple for a number of years and now I have several compelling reasons to get back into the thick of parts of Maple.

I constructed a very simple ODE model of dropping a mass from a height h and letting it hit a massless platter on a spring, with the other end of the spring connected ground.  One...

f :=  (0.1953125000e-2+.3750000000*(RootOf(-512*x-7+192*_Z^(2/3)+24*_Z^(1/3)+512*_Z-6*(512*_Z+192*_Z^(2/3)+24*_Z^(1/3)+1)^(2/3)+12*(512*_Z+192*_Z^(2/3)+24*_Z^(1/3)+1)^(1/3))^(2/3))+0.4687500000e-1*(RootOf(-512*x-7+192*_Z^(2/3)+24*_Z^(1/3)+512*_Z-6*(512*_Z+192*_Z^(2/3)+24*_Z^(1/3)+1)^(2/3)+12*(512*_Z+192*_Z^(2/3)+24*_Z^(1/3)+1)^(1/3))^(1/3))+RootOf(-512*x-7+192*_Z^(2/3)+24*_Z^(1/3)+512*_Z-6*(512*_Z+192*_Z^(2/3)+24*_Z^(1/3)+1)^(2/3)+12*(512*_Z+192*_Z^(2/3)+24*_Z^(1/3)+1)^(1/3)))^3

Hi, im having some trouble with Math182_Lab_4_2007W.pdf with question 7, its giving me hints on how to set up my X and Y from the old points of x1 and y1, but my instructor forgot to teach us using the map command and im having trouble on what to do next.

i'll include my worksheet, MAT_182_-_Lab_#_4.mw

How to solve this receurrence relation with maple

I found various methods, as listen here http://en.wikipedia.org/wiki/Recurrence_relation, to solve recurrsion relation. For example, methods of undertermined coefficients

But how to use these to solve the the above recursive relation.

Hello

I'm trying to animate a DEplot3d, but is that even possible? If it is, how?
