Instructions
Please read the instructions carefully;
1) Quiz will consist of Multiple Choice Questions (MCQs).
2) You have to attempt the quiz online. You can start your attempt anytime within given duration of four days by clicking the link of Quiz on VULMS.
3) 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.
4) Attempting quiz is unidirectional. Once you move forward to the next question, you cannot go back to the previous one. Therefore before moving to the next question, make sure that you have selected the best option.
5) 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.
6) If any student failed to attempt the quiz in given time then no re-take or offline quiz will be held.
7) Use latest version of Internet Explorer or Google Chrome.

Which of the following reason(s) lead towards the numerical integration methods?
Analytical evaluation of integral is very complicated
Analytical evaluation of integral is impossible
Integrand is given in tabular form
All
We prefer ………over the Lagrange’s interpolating method for economy of computation.

none.
If f(x) = 2x, then which of the following is will be derivative of f(x) at x = 0.2?
0.2

The percentage error in numerical integration is defined as
= (Theoretical Value-Experiment Value)* Experiment Value*100
= (Theoretical Value +Experiment Value)/ Experiment Value*100
= (Theoretical Value-Experiment Value)/ Theoretical Value *100
= (Theoretical Value-Experiment Value)/ Experiment Value*100
The step size “h” in numerical integration over the interval [a,b] is defined as
h=(b-a)/n
h=(b+a)/n
h=(a-b)/n
h=(b/a)/n
Two-point formula for the first derivative is defined as
y(xi+h)-y(xi-h)/2h
y(xi+h)+y(xi-h)/2h
y(xi+h)+y(xi-h)/2h
y(xi+h)+y(xi-h)/h^2
Simpson’s 3/8 rule represents the area between the curve y = f(x) in the interval say [a,b] above x-axis by approximating the given curve by the ----------.
Cubic curve through one point
Cubic curve through two points
Cubic curve through three points
Cubic curve through four points
