Hi, I am trying to solve the following differential systems using dsolve numeric but there is something wrong with my code.

I am fairly new to Maple and cant work out why it is telling me that it doesnt work. COuld somebody help me?

 

DifferentialSystem := {diff(r(t),t$2)-r*(diff(theta(t),t)^2=-1000/r^2 ,
                            r(diff(theta(t),t$2)+2(diff(r(t),t)*(diff(theta(t),t)=0,
                            r(0)=sqrt(65), theta(0)=1.446),(diff(theta(t),t)=-6/13(0,0,1),
                            (diff(r(t),t)=(4*sqrt(65))/13};
 
 

That is what I have typed into Maple.
