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
