Using the Black-Scholes formula for the European Call Option, and the Put- Call Parity deduce the Black-Scholes formula for the European Put Option.
Answer:
C = N(d1)S-N(d2)Ke-rT
Put-Call Parity
P = Ke-rt -S -C
P = Ke-rt -S - N(d1)S-N(d2)Ke-rT
P = Ke-rt -N(d2)Ke-rT -S - N(d1)S
P = (1-N(d2))Ke-rT -( 1- N(d1))S
P = N(-d2)Ke-rT -N(-d1)S
