Maxima, Minima and Inequalities- The Basics | |

This is a month of distress; students going into
depression over their marks, everyone asking for attention, frantic phone calls
and emails, long hours of workshops, motivating speeches, exclusive sessions.
In short, bullets flying all around and everyday becoming a war zone. Part of
the game though. This is the month every instructor in the field tightens his
belt and gets ready for the barrage of queries and emotions flying his way.
(And I just burnt my tea I left on the burner 10 minutes ago while writing
this. Oh well!) I am still amazed how crushing those meaningless percentiles
can be to the spirits of the students. I keep on telling students don't take
your percentiles seriously. Don't take your percentiles seriously but my
exhortations always fall on deaf ears. Students are so much caught in this web
that they cannot detect that half their miseries are emanating from something
that is not real and cannot supplant the real thing- The CAT. Oh well, I better
go and answer those distress calls. For all those students telling me that I
have disappeared from TG, here is the new chapter to shush them for a while.
Till the mutiny rises again I shall have to end here and leave the rest of it for my CBT Club students. I shall cover some problems based on this in the CBT Club this week. You might also like: Quadratic Equation Absolute Value (Modulus) Function |

Re: Maxima, Minima and Inequalities- The Basics | |

@TotalGadha: x,y,z are distinct numbers so it can't be 4 4 3. |

Re: Maxima, Minima and Inequalities- The Basics | |

Hi Kunal Yes, you are right. As x, y, z are distinct, none of them can be equal. So 4, 4, 3 is ruled out. I have posted the correct solution in this thread only. You can check it here. Kamal Lohia |
