a) Basic arithmetic operations
Program:
#Asking for the user input
x = int(input ("Enter the first number : " ) )
y= int(input ("Enter the second number : " ) )
#printing the Menu
print("What would you like to do? " )
print("1. Addition")
print("2.Substraction")
print("3.Multiplication")
print("4.Division")
#Asking user about the arithmetic operation choice
n = int(input("Enter your choice " (1-4) " ))
#Calculation as per input from the user
if n == 1 :
print("The result of addition : " , (x+y))
elif n==2 :
print("The result of substraction : " , (x-y))
elif n==3 :
print("The result of multiplication : " , (x*y))
elif n==4 :
print("The result of division : " , (x/y))
else:
print("Invalid Choice")
b) log10(x), sin(x), cos(x)
Program:
import math
#Providing the Menu to choose
print ( "What would you like to do ?")
print("1. Log10(x)" )
print("2. Sin(x)" )
print("3. Cos(x)" )
#Asking user about the choice
n = int(input("Enter your choice (1-3) : " ))
#Asking thre number on which the operation should be performed
x = int(input( "Enter vlue of x : " ))
#Calculation as per input from the user
if n == 1 :
print("Log of" , (x) , "with base 10 is ", math.log10(x))
elif n == 2 :
print("Sin(x) is " , math.sin(math.radians(x)))
elif n == 3 :
print("Cos(x) is " , math.cos(math.radians(x)))
else:
print("Invalid Choice")
