#Variable Declaration:
import math
#Calculations:
#Part 1
th1=math.acos(0)
th=th1*180/math.pi #Calculating theta
#Part 2
Vodc=4.47*4.47*math.cos(th1)/20 #Calculating output voltage
#For theta=+/-30 deg
Vodc1=math.cos(30*math.pi/180) #Calculating output voltage for theta 30
#For theta=+/-45 deg
Vodc2=math.cos(45*math.pi/180) #Calculating output voltage for theta 45
#For theta=+/-60 deg
Vodc3=math.cos(60*math.pi/180) #Calculating output voltage for theta 60
#Results:
print('Theta= + or - %d degree'%th)
print('\nVodc for 30 degree= %.3f V'%Vodc1)
print('\nVodc for 45 degree= %.3f V'% Vodc2)
print('\nVodc for 60 degree= %.1f V'% Vodc3)
