Shahrukh Math

As almost always, my sister did a Shahrukh themed problem set for her math class in honor of his birthday.  And now I will share it with you, to give you all painful math class flashbacks, and make you wish you were in her class.

This is also to make my poor sister feel better, because she showed her class “Chaiyya Chaiyya” as part of her lecture and NO ONE RESPONDED!  They sat there like lumps!  Some of them even fell asleep!!!!!  To be fair, it is a 8am math class and it was the day after Halloween, but STILL!!!!  I promised her I would share the lesson with my blog people and they would be much more enthusiastic.

Before you can do your “homework”, you need the background viewing:





  • Let’s do matrix algebra with Shah Rukh Khan! Shah Rukh Khan has been in lots    of movies and lots of songs. My favorites are “Chaiyya Chaiyya,” “Yeh Tara Woh Tara,” “Pretty Woman,” and “Raula” [see the class Blackboard site for links]. To keep the important details of these songs straight, we can use a matrix!
    • There are three important aspects of a song: the music, the dancing, and the costumes. Rate each song in each of these three categories on a scale of 0 to 5, with 0 being the worst and 5 being the best
    • Write your ratings as a matrix. Each row of the matrix will be a different song, and each column will be a different
    • Multiply your song-matrix by

Matrix1How does what you get relate to your original ratings?


  • Multiply your song-matrix by


How does what you get relate to your original ratings?

  • Suppose your friend feels that the overall quality of a song depends just on music and dancing, and that music is twice as important as dancing. What would you multiply your matrix by to find your friend’s ratings?
  • SRK’s birthday is Nov. 2. How do you plan to celebrate?




Let’s see how you all do on these questions, and my sister can use that as a baseline for grading the homework.  And if the disappointing reaction of her morning class doesn’t scare her off, I may also share the Calculus problem set she will do for the afternoon class.

    Just to demonstrate that I actually read the whole problem, there seems to be a typo. The second sub-dot-point sentence appears to end prematurely. Did something get dropped off?



  2. You’ll be relieved to hear that subsequent classes were more enthusiastic. Apparently the early morning class was still recovering from Halloween festivities…
