Hi everybody,how can I solve these equations in Maple and plot the answers? tnx...

eq1 := diff(x(t), t) = 35*(y-x)

eq2 := diff(y(t), t) = -x*z-7*x+28*y

eq3 := diff(z(t), t) = x*y-3*z

Hi everyone...

How can I plot the below function: 

x^2+(y-x^(2/3))^2 = 1;

tnx...

Hi erverybody:
How can I get the Laurent serie for function f(x)=1/(1-x^2) about x=1 with condition: abs(x-1)<2
tnx...

Hi everyone:

I want to write the below serie in Maple, how can I do it?

where: k = 0,.....,n

n is a Natural number.

tnx...

Hi:

How can I solve this system with numerical method:

eq1 := diff(f_n(zeta), zeta$2)-h_n(zeta)*(diff(f_n(zeta), zeta))-f_n(zeta)^2+g_n(zeta)^2 = 0;
eq2 := diff(g_n(zeta), zeta$2)-h_n(zeta)*(diff(g_n(zeta), zeta))-2*f_n(zeta)*g_n(zeta) = 0;
eq3 := 2*f_n(zeta)+diff(h_n(zeta), zeta) = 0;
ics := f_n(0) = 0, f_n(10) = 0, g_n(0) = 1, g_n(10) = 0, h_n(0) = 0;
tnx...
