Hi, is it possible for maple to isolate a variable quotient (with one command)?

i.e. for the expression

eq:= 0 = g-b*v_t/m

-> b/m = g/v_t

I tried this:

isolate(eq, b/m);
 

and got

"Error, (in isolate) 0 = g-b*vt/m does not contain b/m"

if however I isolate for b and then divide by m i get whats required:

isolate(0 = g-b*v_t/m, b)/m;
b/m = g/v_t

is there a more direct way?

 

Dear Sir/Madam I heared that the classic part of maple 11 is more faster than Maple 12 so I decide to install maple 11 but: I cannot install maple 11 in my Notebook. When I Doubleclick on installation it start to extract. but when it reached 100% disappears! I also tested the second theory. in temp folder I double clicked the extracted setup application in windows directory. but no response too! What I need before installation? In addition, after that I installed Maple 12 seccessfully! without any problem! And Also I can Install maple 11 in my office's PC.

write a program that finds three norms for a given vector?

Can't seem to figure out how to change the background colour of a worksheet.

It's not a simple right click on the background as one would think as that option is not available.  And it's not in the tools option menu.  Can it be done?

 

please help me in finding the pattersn in the series:

 

-1 / 6 + 1 / 20 - 5 / 84 + 7 / 216 - 47 / 1320 + 37 / 1560 - 319 / 12600 + 533/ 28560 - 1879 / 95760 + 1627 / 105840 --...

 

thanks

I wanted to try this example of Maple's help, but it gives an error message:

restart;

with(algcurves);

f := y^2-x*(x^2-1);

plot_real_curve(f, x, y, showArrows = true);


Error, (in algcurves/CurvePlot:-PlotRealCurve) too many levels of recursion

Hello

I'm interested in passing programs from Fortran to Maple, I have some queations:

 

1) Is it true that maple can only understand functions, and doesn't understand subroutines?

2) If Fortran function uses commands like "exp" "max" etc, is it okay?

3) If Fortran function uses external libraries (.lib, .dll) do I need to combine then somehow with the dll file I'm preparing for Maple? How?

When I plot a parametric surface:

S5 := PositionVector([VectorCalculus[`*`](u, v), VectorCalculus[`+`](u, v), VectorCalculus[`+`](u, VectorCalculus[`-`](v))], cartesian[x, y, z])

VectorCalculus[PlotPositionVector](S5, u = VectorCalculus[`-`](1) .. 1, v = VectorCalculus[`-`](sqrt(VectorCalculus[`+`](1, VectorCalculus[`-`](u^2)))) .. sqrt(VectorCalculus[`+`](1, VectorCalculus[`-`](u^2))))

please help me here:

can we simplify the answer of the following command:

diff(arctan(sqrt(b*a)/b)/sqrt(b*a), `$`(b, n))

 

thanks

I used convert(problem,parfrac,x) and it gave me an error saying augment not a rational function.

(3x - 1) / x(x-1)

want to diplay it like this

A/X + b/(x-1) then coming up with the answer like this 1/x + 2/(x-1).

Newb to maple and this is my first post. Thanks

please help me here:

 

how can we find:

sum((5/2+2310*n^5+5775*n^4+5019*n^3+(3507/2)*n^2+(409/2)*n)/(27720*n^7+97020*n^6+132300*n^5+88200*n^4+29400*n^3+4410*n^2+210*n), n = 1 .. n-1)

 

Maple is giving answer which is very complex

please help me here:

we want to find:-

sum((5/2+25*n^2+25*n)/(300*n^4+600*n^3+360*n^2+60*n), n = 1 .. n-1)

maple gives me an answer which looks complex to me? can we simplify it further?

 

thanks

 

I'm trying to do this project but I keep getting an error message...does anyone have any ideas???

 

I find it much easier to enter equations in the Text mode (red bold text). In the past I found a UI setting that allowed me to stay in this mode, but now I can't remember where to find the option...so every time after I input a command, the next command is back in Math mode by default. How can I make it stay in Text entry mode all the time?

Hello, I have a function that produces different phase portraits as you change the variable x in the original equation. Im trying to find out at what values of x this change occurs...
 

So far I have determined the eigenvalues with regards to x and have run loops to find out roughly when this happens but i would like to be able to do this with either a procedure of perhaps dsolve or solve maybe?

 

So, given the eigenvalues, how would i go about doing this?
