Question
Need some help with Matlab just need the code how to find the differential equation and if you want the ezplot graph. just to see what i'm missing... i know the work I just NEED TO KNOW HOW to do it in MATLAB.
Suppose a resisitor R=3 ohms a capacitor C= 5*10^-3 farads, and an inductor L = 10^-2 henrys are connected in an electric circuit with a 110 volt, 60 HZ alternating generator. Find the steady periodic current i _sp (t) . I know Omega w = 2pi and 60 HZ = 120 pi and the initial value problem is
10^-2 q" + 3q' + 200q = 110cos(120pi * t) , q(0) = 0 = q'(0)
This is the steady state-periodic charge, but to find the steady-periodic current we need to differentiate. since 120pi * 6.61 * 10^-2 = 24.9 and -sin(theta) = sin(theta - pi) we obtain
AGAIN i just need help with the Matlab coding and graphing. THANK YOU.

THANK YOU.Explanation / Answer
t=sym('t')
i_sp = diff(6.61*10^(-2)*cos(120*pi*t-3.134)) % it will give the current expression
ezplot(i_sp) % it will plot the current graph
