That is sort of a mix between formula response and numerical response.
From the physics, in this case, 500 needs a unit, for example Hz,
along the lines of
(-4A)cos(500 Hz*t)
I would suggest just using variables all the way, along the lines of
I=4A
w (for omega) = 500 Hz
LON-CAPA can deal with
I*cos(w*t)
as an answer when you use formula response, and realize that that is
for example the same as
cos(t*w)*I
