Hi,

How do I ask maple to differentiate y^2+(x-c)^2=c^2 w.r.t.  x ?

it's defnitely not implicitdiff

I think I knew this before...then I just cant remember...

Thanks in advance.

> c:=-4:
> FM1:=DEplot(diff(y(x),x)=-c/x^2,y(x),x=-10..10,y=-10..10,color=red):
> FM2:=DEplot(diff(y(x),x)=x^2/c,y(x),x=-10..10,y=-10..10,color=green):
> display(FM1,FM2);

how can I join the direction fileds together?

i mean just like plooting the solutions of the ODEs..

I want to do with "linestyle"..tried, but dosent seem to work...

Hi,

I am using Maple 11.02 on win xp sp2 in classical worksheet

I put

restart:

ode:=2*diff(y(x),x$2)-y(x)/x+y(x)^3*cos(x);
 

dsolve(ode,y(x));

maple give me nothing at all  ?? just like I typed  " : " instead of  "  ;   "

why?

Thanks

Hi,

I have been doing some ODEs question and I want to check them with Maple 11Classical Worksheet  in windows xp sp2.

>restart:

>ode:=diff(y(x),x)-y(x)=x*y(x)^5;
 dsolve(ode,y(x));

then the output got 4 answer

I was wondering if there is something to keep it in the form like

y^4 = f(x)  ??

Thanks in advence

Hey,

I have an ODE:

diff(x(t),t$2)+epsilon*diff(x(t),t)+x(t)=0

where 0<epsilon<<1

is there a way to plot a phase plane of this?

or I will just have to give epsilon a really really small value to plot that?

thanks in advance
