capacitor stuff

how does one decide whether a capacitor is a differentiator or inductor??
the capacitor equation is i = cdv/dt....or equivalently v =(1/c)(integral)i???

i know this is lame..but....i am helpless??

Capacitor Stores the energy in the form of Voltage and Inductor in form of Current....

kekekeke.. it should be a differentiator or integrator ( not Inductor)
It's how the RC circuit is used that determines it's function.
Differentiator produces positive and negative spikes from an applied square wave, and a integrator, produces a ramp up trangular wave form.
U can understand it better with a scope

oh sheesh ...mistake

but i still didnt get it....how do i decide whether a given circuit is a differentaitor or integrator..?? do bode plots help??
