i have have no idea how to start,this is not not home work, thus, i asked for help.

Answer 1

[KSSV]

N = 500 ;

t = linspace(0,7,N) ;
i = @(t) 0.3+0.1*exp(-5*t).*sin(25*pi*t) ;   % current

i = i(t) ;

plot(t,i) ;

Read about sum, trapz to get the integration.

[mat lab]

thats the integration of V(t) ? for that integration would i need to differentiate i(t)dx ?
