I have a 2nd-order differential equation dEq and a set of initial conditions initC. I solved the equation by: soln := dsolve({dEq, initC}, numeric) the solution should be in the form r(theta) = blah blah Now I want to plot a graph of theta and r so I used with(plots); polarplot(soln, theta = 0 .. 2*Pi); which didn't work out!! I don't know what might be the problem. Please help thanks
