In this exercise, you will design more of the circuit-based wumpus agent.

a. Write an equation, similar to Equation (7.4), for the Arrow proposition, which should be true when the agent still has an arrow. Draw the corresponding circuit.

b. Repeat part (a) for Facing Right, using Equation (7.5) as a model.

c. Create versions of Equations 7.7 and 7.8 for finding the wumpus, and draw the circuit.
