MaplePrimes Questions

if i have a saved single plot without any programing codes, how is possible to add a verical text for it's vertical axis label?
why isn't possible to copy a whole plot in maple 13 and paste it in another locationof that page or another new blank tab, whereas in maple 12 was possible!?
Hello, I was wondering if someone could help me with the following problem. I have a procedure AAP:=proc(A, titel) local a,b,c,d; a:=A; b:=[solve(t^3-a=0,a)]; c:= (z-L[1])*(z-op(2,L))*(z-op(3,L)): plot3d(pol(0), dsc(2), hsv( carg(F),1,1),ori,nweb,grid=[100,100], title=titel) end proc: for j from 1 to 8 do AAP(j,Figure j+1) end do;

Hi,

I am trying to reuse a function that I computed numerically (using dsolve).

My dsolve line is something like this

Sys:=dsolve({f1(0)=0,diff(f1(x),x)=...},{f1(x)},numeric}

Then I want to define a new function as follows:

g(x):=2*f1(x/2) and use it in solving another ODE system.

How can I do that?

I could solve the ODE only numerically.

Thank you.

the equation is like the pic below:

int(sqrt(1+16*a^2*y^6+24*a*y^5*b+16*a*y^4*c+8*a*y^3*d+9*b^2*y^4+12*b*y^3*c+6*b*y^2*d+4*c^2*y^2+4*c*y*d+d^2), y = 0 .. .2)

i try it by Maple ..but did not get any answer of it ! anyone can help me with this ??or there is no real answer for it ?

since the equation got 4 unknown constants which are a,b,c,d ...so how to use maple to solve it ???

any idea and comment will be much appreciated ...thx

Hi all,

I have a relatively simple question that you can do by hand, but I want to know, if it is possible for MAPLE to compute directly with a single command if any 2 vector functions do intersect.

eg. r(t) = <cos t, sin 2t, exp(t)> s(t) = <sin t, cos t, exp(t)> ,  -2 < t < 2

thanks in advance

Hello, I was wondering if someone could help me recreate the picture found on http://en.wikipedia.org/wiki/Complex_logarithm Thank you in advance, Herman

Good Evening Everyone,

Would any body be kind to help me with the attached file. My goal is to plot the frequency graph with different sets of variables for a vertical pump on a pile cap to avoid resonace.

Regards,

Moses

Mam do wykonania kilka zadan lecz niestety nie wiem jak się za nie zabrac. Proszę o jakiąkolwiek pomoc. Oto zadania. 1)Ile jest liczb pierwszych mniejszych niz 567! ? 2)W zbiorze liczb naturalnych {1, 2, ..., 123456!} znajdz wszystkie liczby podzielne przez 13 i 15. Wynik zapisz w postaci zbioru. 3)Czy pierwiastki nastepujacego wielomianu w(x) = x^6 + x^4 + x^2 + 1 leza na okregu jednostkowym? 4)Ile jedynek ma liczba 235465656! w systemie dwójkowym? 5)Zdefiniowac funkcje f(x) = x^234321+cos(x)+ln(x) i obliczyc 10-ta pochodnafunkcji f w punkcie 100.

The question is simple.

How could I find an earlier (not Active) forum topic?

(I use Firefox 3.5 on xp.)

Thanks,    Sandor

 

Hi I have the expressions: I1 := M*[1-a*exp(-i*theta)]/(1-b*cos(theta)) I2 := M*[1-a*i*exp(i*theta)]/(1+b*sin(theta)) I3 := M*[1+a*exp(-i*theta)]/(1+b*cos(theta)) I4 := M*[1+a*i*exp(i*theta)]/(1-b*sin(theta)) x1 := M*[1-a*cos(theta)]/(1-b*cos(theta)) x2 := M*[1+a*sin(theta)]/(1+b*sin(theta)) x3 := M*[1+a*cos(theta)]/(1+b*cos(theta)) x4 := M*[1-a*sin(theta)]/(1-b*sin(theta)) y1 := M*a*i*sin(theta)/(1-b*cos(theta)) y2 := M*a*i*cos(theta)/(1+b*sin(theta)) y3 := -M*a*i*sin(theta)/(1+b*cos(theta)) y4 := -M*a*i*cos(theta)/(1-b*sin(theta)) I enter the following expression

Please Ignore the previous posting, I had a few mistakes.

I have the following terms: >

a := .178131; 0.178131 >

b := -0.6814e-1*`if`(t = 0, 6, `if`(t = 1, 10, `if`(t = 2, 15, `if`(t = 3, 20, NULL))));

 c := 0.16242e-1*`if`(t = 0, 6, `if`(t = 1, 10, `if`(t = 2, 15, `if`(t = 3, 20, NULL))))^1.5;

The ODE is:
