E(t)=Ri(t)+1/C ∫?i(t) dt
i(t)=dq(t)/dt ∫?dq(t)/dt dt=q(t)
E(t)=R dq(t)/dt+q(t)/C
L[Rq^' ]=RsQ(s)-Rq(0)=RsQ(s)
L[q(t)/C]=Q(s)/C L[E]=E/s
E/s=RsQ(s)+Q(s)/C=Q(s)(Rs+1/C)
Q(s)= E/s 1/(Rs+1/C)=E/s(Rs+1/C) =(E/R)/s(s+1/CR) =E/R 1/s(s+1/CR)

(x+1)^2020=(x+1)^(2?1010)=(x^2+2x+1)^1010 =((x^2+1)+2x)^1010
((x^2+1)+2x)^1010

?+1010(x^2+1) (2x)^1009+(2x)^1010
(2x)^1010以外の項はx^2+1の倍数なのでpを適当な整数とすると
((x^2+1)+2x)^1010=p(x^2+1)+(2x)^1010……?

(2x)^1010=(4x^2 )^505=((4x^2+4)-4)^505
