I have a problem with my calculations. I have changed the Order to 15. If I go any higher than this I get the error message:
"Error, invalid input: rhs expects 1 argument, but received 0"
after the loop. I need to calculate more terms. Does anyone know why this is happening and how I can fix it?
This is the spreadsheet
How to find the total derivative of h(x,y,z) = (x+ y - z, sin(xyz) + e).
maple help shows partial derivative explanation but has not much for total derivative. I haven't learned total derivatives yet so any help is thankful.
Maybe this is a stupid question but if I have a function
how do I differentiate V with respect to t1 diff( V , t1) ?
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 :
dont call mysimplify.
But it works if I call it directly
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)
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
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)
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?
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
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 tAC. I've tried allvalues(%) and convert(solAC,radical) but none of these would work. Do any of you have more useful ideas?
My Maple version is 11.02.

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.");
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(%);
i have an equation which is something like
I need to write the coefficients an in a table against the power of R
so something like
my table should go up to n=15
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.
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?

The text below was encrypted with a substitution cipher. Only the letters (both
upper-case and lower-case) were substituted, leaving punctuation and spaces alone.
Can any on help me to figure out what the original message was using maple procedures.

I have no clue...
hey i'm trying to learn how to use maple and can't seem to figure out why this is wrong. i don't really know what "nops()" does either.
*insert equations, matrix and Groebner here and get a whole bunch of z values *
for i from 1 to nops(zvals)
