I have got the following error after the plot statment

plot(eval(N(y), nsol), y=-1..1);

so what is the matter?

Error, invalid input: eval received sol, which is not valid for its 2nd argument, eqns

Thanks Joe it works but i got a very big solution

is there any way to simplify the result

then how can i get a numerical solution for the same problem and plot the results
