Hi everybody
I am a newcomer in the mathematica world and I have been facing an issue for some days.
I have used mathematica to solve an NDSolve and it has worked well
I have tested expressions with the solution of NDSolve and its has worked well.
Now if I use an expression in an "Conditional If", it does not work.
Thank you for your help
See below
signy[t_] := y[t] /. orbit where y[t] is the solution of the NDSolve
signy[1]
{-1.96861}
ang12[t_] := If[signy[t] > 3, 10, 6]
ang12[1]
If[{-1.96861} > 3, 10, 6]
