I want the asymptotics for EllipticF(z,k) w.r.t. z (yes, not k).

My example is F:=I*EllipticF(c*I/x,k), c=2-2^(1/2),k=3+2*2^(1/2)
and I want the limit x ---> 0+.

  MultiSeries:-limit(E,x=0);

results in 0.54... + 0.54...*I (real = imag, positive value).

  MultiSeries:-series(E,x,3);

gives (after clearing the output) the same for setting x=0.


For Numerics my setting is Digits:=24 and eps:=1/10^18.

  subs(c=2-2^(1/2), k=3+2*2^(1/2), F...

Hello,

I have a question on the efficient usage of map command.

 

Suppose I have a function of two variables:

a:=(x,y)->sin(x)*cos(y)

 

I would like to evaluate the function using fixed values of x and y (i.e. grid search problem):

f:=x->x*Pi/180

X:=f(<seq(0..360,45)>)

Y:=f(<seq(0..360,60)>)

Suppose that the Hamiltonian is invariant under time reversal:

[H,T] = 0.

Show that, nevertheless, an eigenvalue of T is not a conserved quantity.

Hi guys. I have a sets of N data points in the form [x_component(1), y_component(1)], [x_component(2), y_component(2)], ... [x_component(N), y_component(N)] that I want to plot as points and draw the regression line through them. I know how to plot the regression line with the data points in the form [x_component(1), x_component(2), ..., x_component(N)] and [y_component(1), y_component(2), ..., y_component(N)] So my question is how to isolate all the x components and all the y components from my data points?

Hi,

How can I create a help file in maple for a user function ?

Thanks

How do I get rid of the right-hand pallete dock ?

Hello,

 

this problem has been bugging me for months. I am defining functions with "if" in their definition.  These functions seem to be well defined, without any problem. Then I do sum and something goes wrong.  I have tried to isolate the problem to give you an example:

 

Hello, I am new to Maple, and I have a novice question on rounding with evalf function.

 

I have an expression:

m:=(x,y)->126*cos(a)^2*(cos(x)-sin(x)*cos(y+b+c)*tan(a))-42;

 

Then I set some parameters as constants:

g:=x->x*Pi/180;

a:=g(58); b:=g(-45); c:=g(100);

 

Hi Friends,

 

May I know How do I solve numerical differntial equation in MAPLE 12..?

My equation is very big..please send your valuable suggestion

 

Thanks

What is the value of u1 in this u substitution to go from -2*Pi*(int(sqrt(-3*u^2+4), u = 1 .. 0)) to -2*Pi*(int((4/3)*sqrt(3)*cos(u1)^2, u1 = (1/3)*Pi .. 0))? I'm just not seeing it.

 

Is it possiobe til split a function into multiple varriables? I have seen something like this is a maple function "tools->assistants->backsolver".

Does anyone have a clue how thats done? I need it to my dynamic function ^^

Hi,

How can I write a command that the Maple assigns the numerical solutions of the dsolve command in a procedure such as the simple following procedure?

Maple solves the 4 equations for the 4 unknown, although I eventually need to end up with just the real part. Maybe I am doing something wrong. Once I get to the bottom of this worksheet and begin to try to extract (ie copy) each A1, A2, B1, B2, it freezes, my system stops functioning, to the point where I have to shut it down and restart it. Trying a few times, I see that, once I load this worksheet in, and begin at restart, once it does the last calculation, if I right click

Maple generates the values (numbers) for axis labeling automatically, e. g. 3.5   10E-3 for 3.5 meters. If I want to label the axis manually with millimeters, how can I fit the automatically generated numers to the manual given unit?

Assume n is positive integer.

dsolve((1-x^2)*(diff(y(x), x, x))-2*x*(diff(y(x), x))+(n*(1+n)-n^2/(1-x^2))*y(x), y(x))

Maple says

y(x) = _C1*LegendreP(n, n, x)+_C2*LegendreQ(n, n, x)

However

 dsolve((1-x^2)*(diff(y(x), x, x))-2*x*(diff(y(x), x))+(n*(1+n)-n^2/(1-x^2))*y(x), y(x), 'formal_solution', 'coeffs' = 'mhypergeom')

Maple says

y(x) = _C1*(Sum((-1)^(2*_n1)*GAMMA(_n1-(1/2)*n)*x^(2*_n1)/GAMMA(_n1+1), _n1 = 0 .. infinity))/GAMMA(-(1/2)*n)
