Can any on help me to figure out what the original message was using maple procedures.

I have no clue...

How do you calculate the final velocities and the angles when two objects collide into one another...any help/info would be highly appreciated.

When storing an inequality, Maple seems to always convert it to less than or less than or equal form.

x:=a>b  => x:= b<a;

Is it always true? Can someone explain a little bit how maple stores its data?

 

Thanks,

so far i plotted functions where z values were functions z=f(x,y) in cartesian coordinates. this was easily done with the plot3d command. now i have a function described in polar coordinates, z=f(r,phi). so far i haven't succeded in plotting it. as far as i see it cylindrical coordinates would be required here, but maple expects r=f(z,angle) and i need z=f(r,angle). maybe a changecoords operation would help, but I'm not sure how to perfrom that (I've just started using maple). would be thankful for pointers on how to tackle my problem.

i have an equation which is something like

F''(1)=a0+R*a1+R^2*a2+R^3*a3+...R^n*an

I need to write the coefficients an in a table against the power of R

so something like

n        an

0        ....

1       ....

2       ....

my table should go up to n=15

thanks

Can it be done simpler/better/faster?

F3 := proc (n) options operator, arrow; ln(n)*mul(evalf(1-1/i), i = seq(ithprime(i), i = 1 .. n)) end proc; F3(100000); evalf(%);

F2 := proc (n) options operator, arrow; -ln(ln(n))+add(evalf(1/i), i = seq(ithprime(i), i = 1 .. n)) end proc; F2(100000); evalf(%);

F1 := proc (n) options operator, arrow; ln(n)-add(evalf(ln(i)/i), i = seq(ithprime(i), i = 1 .. n)) end proc; F1(5000); evalf(%);

how to write a procedure that counts ferquency of used letters in a string of a text for ex in this txt: fregs("I have the best dog.");

Hello all,

I'm fairly new to Maple and this problem has had me puzzled for hours now. I simply want to solve an algebraic equation, but I get 6 RootOf solutions. I need a numerical value. I've already tried a couple of things (and browsed these forums) but I haven't been able to achieve this...

I have included my worksheet so you know what I'm talking about.

The value I'm trying to find is t_AC. I've tried allvalues(%) and convert(solAC[1],radical) but none of these would work. Do any of you have more useful ideas?

My Maple version is 11.02.

Please somebody can help : I have a matrix of 50x2 and I want to show her like another matrix of dimensions 17x6 Thanks for your help

How do I get Maple to display the result in lowest terms?  Maple is multiplying the numerator and denominator by 10000.  The answer is correct, but how do I prevent the numbers from being multiplied by 10000?  Do I have a setting or preference set incorrectly?

 

Hey guys, I am trying to plot a direction field using Maple 11.: //*** first I define the spline, this is the function that is giving me the error with(CurveFitting); BasinArea := H -> Spline([[-10, 36000000], [-8, 47000000], [-6, 57000000], [-4, 70000000], [-2, 81000000], [0, 89000000], [2, 95000000], [4, 100000000], [6, 105000000], [8, 111000000], [10, 125000000]], H, degree = 3) ; //*** then I define the two other functions that are used in the DE (error is not in these but I include them for //*** completeness)

I have created a user simplify procedure

`simplify\mysimplify` := proc(fun) ... etc ...

It works correctly, but not when i add it in a module.
ie a call as :

with(MyModule); simplify(x^2+x,mysimplify)

dont call mysimplify.
But it works if I call it directly

with(MyModule);
`simplify\mysimplify`(x^2+x);

I think I miss something but i can't point the error. What is the correct declaration ?
(the module is correct, others procedure works fine)

Maybe this is a stupid question but if I have a function

 

 

how do I differentiate V with respect to t1 diff( V , t1) ?
