So, when there is a capacitor at the input to the inverting terminal and a resistor with one side connected to the inverting terminal and the other side to the output, we have a differentiator circuit. In the differentiator circuit the input is connected to the the inverting output of the Op-Amp through a capacitor(C) and a negetive feedback is provided to the inverting input terminal through a resistor(Rf), which is same as an integrator circuit with feedback capacitor and input resistor being replaced with each other. So, the circuit errs to the extent that the output moves away from ground; but of course it must move away from ground to give us an output. When we meet operational amplifiers, we will manage to make nearly-ideal integrators, and pretty good differentiators.
