1. (10 points) Complete problems 3.64 from the textbook (pp. 174-175). For finding VTH, you are

welcome to use either nodal analysis or mesh analysis; either method will work in all cases, but

sometimes one is easier than another. Also, remember that a dangling resistor at the output will not

affect VTH, as this is the open-circuit voltage, but it will affect RTH, which is the resistance seen looking

back into the circuit from the output terminals.
