Create a menu driven program using user defined functions to implement a calculator that performs the following:

a) Basic arithmetic operations(+,-,*,/)

b) $\log _{10}(\mathrm{x}), \sin (\mathrm{x}), \cos (\mathrm{x})$

Here’s a basic menu-driven calculator program implemented using user-defined functions in Python:

import math

# Function to add two numbers
def add(a, b):
    return a + b

# Function to subtract two numbers
def subtract(a, b):
    return a - b

# Function to multiply two numbers
def multiply(a, b):
    return a * b

# Function to divide two numbers
def divide(a, b):
    if b == 0:
        return "Division by zero is undefined"
    return a / b

# Function to calculate log base 10
def log10(x):
    return math.log10(x)

# Function to calculate sine of an angle in radians
def sine(x):
    return math.sin(x)

# Function to calculate cosine of an angle in radians
def cosine(x):
    return math.cos(x)

# Menu driven program
def calculator():
    while True:
        print("\nMenu:")
        print("1. Add")
        print("2. Subtract")
        print("3. Multiply")
        print("4. Divide")
        print("5. log10")
        print("6. sin")
        print("7. cos")
        print("8. Exit")
        
        choice = int(input("Select operation: "))

        if choice == 8:
            print("Exiting...")
            break
        
        if choice in [1, 2, 3, 4]:
            a = float(input("Enter first number: "))
            b = float(input("Enter second number: "))

            if choice == 1:
                print("Result: ", add(a, b))
            elif choice == 2:
                print("Result: ", subtract(a, b))
            elif choice == 3:
                print("Result: ", multiply(a, b))
            elif choice == 4:
                print("Result: ", divide(a, b))
        
        elif choice in [5, 6, 7]:
            x = float(input("Enter the number/angle in radians: "))

            if choice == 5:
                print("Result: ", log10(x))
            elif choice == 6:
                print("Result: ", sine(x))
            elif choice == 7:
                print("Result: ", cosine(x))
        
        else:
            print("Invalid choice, please try again.")

# Run the calculator program
calculator()

Explanation:

• Basic Arithmetic Functions: add(a, b), subtract(a, b), multiply(a, b), and divide(a, b).

• Mathematical Functions: log10(x), sine(x), and cosine(x) use the math module to perform these operations.

• The Menu Driven Program interacts with the user to select an operation, takes input numbers, performs the operations, and displays results.

• The program will run in a loop until the user selects the option to exit.
