Hello everyone.
I tried to verify my solutions of Differential Equations today and I keep getting wrong results, at least I believe so.
there is obviously a solution of c=1
and here it should be "y(t)=c1+cos(2t)/4" instead.
Interesting enough, if you change 2 to 3 you will get a good result.
Of course here it doesn't calculate a particular solution either (eg. for given y=2 when t=(pi)/2).
