1. Apply Kirchhoff's voltage low (KVL) if R 10, L = 0.1 H, C= 0.01 F and
V=10.
2. Write the 2nd order differential equation (DE) that describe the current of the
circuit (i).
3. Solve the DE to find the current (i) assume i(0) = i'(0) = 0.
4. Replace the DC source with AC source V = 10sin40t then solve the DE.
