please I need help with Python programming

Exercise 2.3: Write a program to perform the inverse operation to that of Example 2.2. That is, ask the user for the Cartesian coordinates x,y of a point in two-dimensional space, and calculate and print the corresponding polar coordinates, with the angle 8 given in degrees. CHAPTER 2: PYTHON PROGRAMMING FOR PHYSICISTS interchange such cases the words package and module are often used in is given to usingel oordinates y this? The appropriate steps are: EXAMPLE 2.2 CONVERTING POLAR COORDINATES Sup the position of a point in two-dimensional space candinates and we want to convert it to Cartesiance would we write a program to do this the appropriate ste 1. Get the user to enter the values of r and e. 2. Convert those values to Cartesian coordinates using th e the standard for las: r=rcose, y rsin. 3. Print out the results. Since the formulas (2.1) involve the mathematical function going to have to import those functions from the math pack the program. Also, the sine and cosine functions in Python ( computer languages) take arguments in radians. If we want the angle in degrees then we are going to have to convert from radians, which means multiplying by and dividing by 180 Thus our program might look something like this: tions sin and cos we he package at the stand thon (and in most other If we want to be able to ente nvert from degrees to File: polar.py from math import sin, cos.pi r = float(input("Enter r: ")) d = float (input("Enter theta in degrees: ")) theta = depi/180 x = r*cos(theta) y = r*sin(theta) print("x =",," y =",y) Take a moment to read through this complete program and make sure you in derstand what each line is doing. If we run the program, it will do something like the following: Enter r: 2 Enter theta in degrees: 60 x = 1.0 y = 1.73205080757 (Try it for yourself if you like.)
