Question

You need to write this program providing function definition. You can choose your own function definition. Write a program that will ask the user to provide an angle value and the program will calculate the sine, cosine and tangent of that angle. (in python)

Answer 1

Below is the python3 code for mentioned problem statement.

import math

# Method to find the sin(angle)
def findSinTheta(angle):

    return math.sin(math.radians(angle))

# Method to find the cos(angle)
def findCosTheta(angle):

    return math.cos(math.radians(angle))

# Method to find the tan(angle)
def findTanTheta(angle):

    return math.tan(math.radians(angle))

if __name__ == '__main__':
    # Prompt for user input to enter angle
    theta = int(input("Please enter the angle : "))
    print("Angle is : ", theta )

    # calling the respective functions
    sin_theta = findSinTheta(theta)
    cos_theta = findCosTheta(theta)
    tan_theta = findTanTheta(theta)

    # Dsiplaying the results
    print("\nSin of ",theta, " is : ",  sin_theta)
    print("Cos of ",theta, " is : ",  cos_theta)
    print("Tan of ",theta, " is : ",  tan_theta)

Output:

Please enter the angle : 30
Angle is : 30

Sin of 30 is : 0.49999999999999994
Cos of 30 is : 0.8660254037844387
Tan of 30 is : 0.5773502691896257

Please find the screenshot of code and output:
