I am given an ideal OP-AMP like this (R-resistor, Cap-capacitor):
and V in is given as a step function like so:
that is V(in) is -2 on [0,1] and then 0 further. I need to find V(out) at 2sec.
So far I think I got the expression I need to work with.
V(out) = -Vc
Vc = 1/(RC) * integral(V in dt)
But my problem is how I deal with a step function in this case of integration. Any help is appreciated.
Thanks.

Code:
/\ (volts)
