If let p=d/dt, 1/p=∫da from -∞ to t then the power absorbed by a capacitor is
p(t)=v(t)i(t)=v(t)Cpv(t)=p[1/2*Cv(t)^2]=pw(t)
Look at the last two terms and apply the 1/p operator from the left. Then ,assuming that w(t) is zero for t<=0 along with voltage and current, we have
w(t)=1/2*Cv(t)^2
"Then ,assuming that w(t) is zero for t<=0 along with voltage and current"
why need this assumption ????
