I'm asked to solve the equations below simultaneously using fsolve.

f := x*exp((1 - x)*a);
f[2] := subs(x=f,f);
eq[1] := f[2] - x;
eq[2] := diff(f[2],x) + 1;

fsolve({eq[1],eq[2]},{x,a}):

fsolve doesn't seem to work here for some reason.

Any help help would be great!

Thanks

Hi all,

I want to solve the following 2 odes simultaneously:

 

ode1:=(1/r^2)*diff(r^2*diff(u(r),r),r) =v(t); (#boundary value problem with 2 boundaries)

ode2:= diff(v(t),t)=u(r); (#initial value problem)

with conditions

IBC={u(0.2)=1,u(0)=0.5,v(0)=0.01}

I am getting error if i use dsolve/numeric. Is there any way/method to solve these numerically using maple packages like dsolve/fsolve...

 

Thanks,
