## Homework Statement:

- the rate of change of the output of both op-amps when the initial energy stored in the circuit is zero and the signal jumps instantaneously from 0 to Vg.

## Relevant Equations:

- SEE ATTACHED IMAGE

I was reading about this 2nd order op-amp circuit which is essentially a cascaded integrator and got confused with the explanation of the book regarding the rate of change of the outputs. The book said that when the initial energy stored in the circuit is zero then

this rate of change is zero when Vo1(0) = 0(initial energy is zero). Now going to the rate of change of the first of amp,

would this also be equal to zero? The reason I asked this is when I derived for this rate of change I ended up with this

the input Vg is a non zero quantity therefore this rate of change can not be zero. But the initial energy stored is zero so this should not be the case. This got me confused. Please enlighten me. TIA!
