A quiz from Lecture 01-06 has been started, its due date is May 2, 2014 (11:59PM). So to avoid any inconvenience in VULMS, you are advised to attempt the quiz before 2 days of Deadline, after 30^{th} of April 2014 no complain will be entertained. Further please do read the following Instructions before attempting:
"Dear student!! You are also advised to recall important formulas from Trigonometry, Differentiation and Integration"
Quiz is based upon Multiple Choice Questions (MCQs).
* You have to attempt the quiz online. You can start attempting the quiz any time within given date(s) by clicking the link for Quiz in LMS.
* The time to attempt the Quiz is limited. Once you login to attempt the quiz, the countdown will start and you have to complete the quiz in given amount of time. So always keep an eye on the remaining time.
* Attempting quiz is unidirectional. Once you move forward to the next question, you can not go back to the previous one. Therefore before moving to the next question, make sure that you have selected the best option.
* If for any reason, you lose access to internet (like power failure or disconnection of internet), you will be able to attempt the quiz again from the position where you left in last attempt. But remember that you have to complete the quiz before expiry of the deadline.
* If any student failed to attempt the quiz in given time then no re-take or offline quiz will be held.
Thanks.

Bht sary answers wrong hain is main. dosri bat ye k ye opr TARIQ Bhai ne jo quiz post kiya wo first 6 lectures main se nhi hai. Ye koi purana quiz hai, Nt the latest from 1st 6 lectures. I request to Tariq bhai k ap wrong answer post na kre jb tk sure na ho. It can mislead the students. Hope u understand....

Question # 1 of 10 ( Start time: 09:52:17 PM ) Total Marks: 1
By using determinants, we can easily check that the solution of the given system of linear equation exits and it is unique.
Select correct option:
FALSE
TRUE
I'll post it's answer later. Currently I can tell that bu using determinants we can check three properties of the system of linear equations which are as follows:
1. Solution exists and it is unique
2. System has infinitely many solution. Assigning arbitrary values to free variable(s), we can get as many solution as we want.
3. System is inonsistent i.e. no solution exists
