One question was about fog.

One question was related to matrix. I was asked to draw matrix of RoS, and then was supposed to take it's transpose.

There was question, in which a Relation was given and I had to check whether it is an equivalence relation or not.

20 mcq's and 6 sub questions 2 of 2 marks, 2 of 3marks, 2 of 5 marks

mcq's were from past papers and book also so read book throughly

sum the series upto nth term 1^2,3^2,5^2....  (5marks)

find the 8th term of G.P (i forgot the values  ) (2marks)

find function (f-g)(x) (2marks)

a set a=(1,2,3) and relation was given and we have to find R(bar)      (3marks)

nad there were two more question also .

BEST OF LUCK

MTH202 Today Paper Mid Term Spring 2013

most of the MCQ's were from previous papers....

Subjective kuch yad hn,,,

Q- Lect-21 ,   2nd last example recursive--- wali ati thi.....

Q- Values were give and I had to draw a Directed grapf of R.

Q- S and R were give and I needed to find the R intersection S. 

Q- A set with 4 elements was given...I needed to find R for that with condition that a < b

also i needed to find R inverse for that 

and draw Directed graph as well for this...
