    I have some doubts in a problem.The problem is on switches (Single Quadrant, 2 Quadrant and 4 quadrant)
    The problem is completely solved but some steps aren't explained.
    I just want to know how did the teacher arrive at those steps.
    I am uploading 2 files. The PDF file has the completely solved problem.
    And the next image file has the portion where I have the major doubt.
    How does the teacher arrive at those 4 equations which is in the image file.
    I would be very grateful if you could throw some more information beyond the problem.
    And I would be really glad if you could explain the whole problem again.
