## to georgios kokovidis...

cant send you a private message so i just post my question about your reply to my post.it just gave the final answer?how do i get the solution?thanks!

## another questions...

thank you georgios kokovidis for acknowledging my question.thank you so much!however i still have questions.can anybody here please help me with this type of questions,im not an engineering or math major,so you can guys say im so bad with math.please help me.this are the questions. sketch the following and convert to rectangular: > 1.)x=t^(3), y=t^(2); 2.)x = (sec t)+2, y = (tan t)-1 3.) r = 2+2sin4thetha 4.) r = 4cos2theta find the dy/dx of the following: > 1.)x=t^(3), y=t^(2); 2.)x = (sec t)+2, y = (tan t)-1 3.) r = 2+2sin4thetha 4.) r = 4cos2theta find the equation of the tangent line to the function with the indicated information:

## Solve a non analtyical function...

I would like to solve a non analytical problem. I dont know the functions behaviour explicity because it involves a number of ranges - if and then statements. How best can I say find the point at which it becomes minimum? Thanks

## questions...

guys please help me with this questions. instruction:determine whether the following converge or diverge {n/n+1} (∑)(2^(n))/(n^(2)) (∑)((n!)^(2))/((2n)!) (∑) (n.3^(2n))/(5^(n-1)) (∑) (-1)^(n+1) n/(n^(2)+4) sum((-1)^n*n*(1/(ln*n)), n = 2 .. infinity) determine where the following power series converge: sum(n*x^n/(n^2+1), n = 2 .. infinity) (∑)(1.3.5.7...(2n-1))/(3.6.9.12...3n)(x-2)^(n) please

## Solving simultaneous equations...

I have the following matrix solution problem. M * v = v where M is a square matrix (integer values). v is a vector of variables whose values I want to solve for. I cannot figure out how I can get Maple to do this. Do I need to use some other software? It seems to me that I should be able to obtain a soltion to the problem. Is there a reason why there may be no solution? Thanks.

## Minimising a function of three variables...

I have a function which comprises a number of sub functions or procedures. E:= (r01,r12,r02) -> VrepR(r01,b01) + VrepR(r12,b12) + VrepR(r02,b02) + VattR(r12,b12)+Vbend(r02); > VrepR := proc(r,b): > rc:= evalf(b*2^(1/6)); if (r

## simple progress bar...

As a simple progress bar, I want to print a dot every time one step of a for loop is finished, for example I tried for i from 1 to nsteps do printf("."); end do: However, this prints all dots at once the moment the complete loop is finished. Using for i from 1 to nsteps do writeline(default,`.`); end do: prints every step a dot, however it includes a new line command (dots appear below each other). Does anyone has suggestions how to make the progress bar? Niels.

## How do I Verify...

I posted this question on the Newbie Forum without success, so I thought I should go ahead and post it here, too. My problem is simple algebra (except there is a lot of it). Every function involved is real, though I'm not sure exactly how to tell Maple that. The equation involves a term under a radical, which I think is the cause of my difficulties. To deal with the radical I use a the simplify/radical command, and I discover that the remaining radical exists in only one term. So I isolate that term on one side of the equation and square the equation. Then I discover that the variable I want to solve for is a common factor, and it appears in even powers. I do a subsitution and end up with a quadratic equation which I solve using the quadratic formula. When I plug the solutions back into the squared equation, I find that they correctly solve that form of the equation. However, when I plug them back into the original equation, I get a mess that I can't seem to simplify. I could use any help you can offer. I will attach a worksheet containing the relevant parts of my work here(with the messiest stuff removed).

## new at maple...

hi my name is john.i just purchased maple last night and can't figure out how to use it can somebody help me do this questions using maple?this are the questions.i need to evaluate this four question.thanks! > int(x/(x^4+9), x = -infinity .. infinity); > int(1/(x-8)^2/3 ,x= -infinity..0); > int(x/sqrt(4-x^2), x= -2..0); > int(1/1-cos(x), x= 0..Pi);

## limit tutor problem...

hi!i tried using the limit tutor for the ff questions but it just said "no rule is applicable for this problem" please help me i dont know what to do..thanks!i appreciate it. > 1.) (lim)(sqrt(x-1)-2)/(x^(2)-25); > x approaches 5 > 2.) (lim)(x+1-(e)^(x))/(x^(3)); x approaches 0^+ > 3.) (lim)(x^(3/(2))+5x-4)/(x ln x); > x approaches infinity > 4.) (lim)tan x ln sin x; x approaches pi^-/2 > 5.) (lim)(cos x)^(x+1); x approaches 0 "6.) (lim)(1+1/(x))^(5x)" x approaches infinity

## substitutions don't substitute...

Hi: I have a complicated expression containing many Maple generated terms each of which typically looks like: 12/b/(b^s)*s/sin(Pi*b)^2*Pi^2 I absolutely can't figure out how to make 1/b/b^s become b^(s+1). I have tried using "patmatch", "match", "subs", "collect" and have now run out of ideas. For example: subs(1/b/(b^s) = 1/b^(s+1),...) does nothing. Can someone please suggest a way to do this so that the end product will look like 12/b^(s+1)*s/sin(Pi*b)^2*Pi^2 Ultimately, I want to identify the exponents of b in each term. Thanks Mike

## format text output of matrices...

Hello all,

only occasionally using maple, I calculated some matrices and vectors numerically with maple and would like to use the output for further processing with other computer programs.

My problem is that the output format created per default is far from being machine readable:

[0. , -0.374388562686400750 10 , -0.374388562686400750 10 ,

-18 -18]
-0.174912303608013020 10 , -0.174912303608013020 10 ]

[ -18 -18
[0. , 0.708119543904595083 10 , 0.708119543904595083 10 ,
