//Initialisation
vcc=15 //voltage
vc=9.5 //voltage
ic=10**-3 //collector current
Ie=10**-3 //emitter current
RE=5.6*10**3 //resistance in ohm
RC=1.3*10**3 //resistance in ohm
R2=13*10**3 //resistance in ohm, choosen R2 as approximately 10 times RE
pi=3.14 //pi
fc=10 //frequency in hertz
//Calculation
rc=(vcc-vc)/ic //resistance in ohm

R1=(R2*(vcc-2))/2 //resistance in ohm
