ASSIGNMENT
Note: Answer all questions. Kindly note that answers for 10 marks questions should be approximately
of 400 words. Each question is followed by evaluation scheme.
Q.1 (i) Let A = {1, 2, 3, 4, 5, 6} and B = {2, 4, 6, 8}. Find A – B and B – A.
(ii) In a group of 50 people, 35 speak Hindi, 25 speak both English and Hindi and all the people speak
at least one of the two languages. How many people speak only English and not Hindi?
How many people speak English?
Answer:
(i) A-B
WINTER 2013
PROGRAM BSc IT
SEMESTER 1
SUBJECT CODE & NAME BT0063-MATHEMATICS FOR IT
CREDIT 4
BK ID B0950
MAX. MARKS 60

2. (ii) n (A U B )= people who speak in either Hindi and English.
Given people speak at least one of the languages.
n (A U B) = 50.
Q.2 (i) Express 7920 in radians and (7π/12) c in degrees.
(ii) Prove that (tan θ + sec θ – 1)/ (tan θ + sec θ +1) = Cos θ / (1-sin θ) = (1+sin θ)/ Cos θ
Answer: (i) The conversion is 180O
= π radian
So 79200
= (7920*3.14)/180 = 138.247 radians
(7π/12) c in degrees:-
(ii). Solution:-
(tan θ + sec θ – 1)/ (tan θ + sec θ +1) =(1+sin θ)/ Cos θ
If (tan θ + sec θ – 1)/ (
Q.3 (i) Define continuity of a point
(ii) Test the continuity of the function f where f is defined by f(x) = {x-2/|x-2| if x ≠ 2, 7 if x = 2.
Answer: (i) Definition of Continuity

3. Let a be a point in the domain of the function f(x). Then f is continuous at x=a if and only if
lim f(x) = f(a)
x --> a
(ii) Test the continuity of the function f where f is defined by f(x) = {x-2/|x-2| if x ≠ 2, 7 if x = 2.
Solution:-L.H.L =limx tends to (x-2)/|x-2|
Put x = 2-h , h=0
Q.4 Solve dy/dx = (y+x-2)/(y-x-4).
Answer:dy/dx = (y+x-2)/(y-x-4) -------------------------------- (i)
Put y = vx
Diff w.r.t “x”
Q.5 (i) a bag contains two red balls, three blue balls and five green balls.
Three balls are drawn at random. Find the probability that
a) The three balls are of different colors’.
b) Two balls are of the same color.
Let nCk = number of ways to pick up k items from a set of n items.
Of course you should already know that nCk+=+n%21%2F%28k%21%2A%28n-k%29%21%29 (*)
Bag consists of 2 red balls (R), 3 blue balls (
Q.6 Solve: 2x + 3y + 4z = 20, x + y + 2z = 9, 3x + 2y + z = 10.

4. Answer: These equations are written as
[2 3 4 [20
1 1 2 = 9
3 2 1] 10]
AX = B
Where A = [2 3 4 , 1 1 2 , 3 2 1 ] X =[
