Q1. State Leibnitz’s theorem. Find the nth derivative of(𝑥)= 𝑥2𝑒𝑎𝑥,
using Leibnitz theorem. [2+8] 10
Answer.
Leibnitz’s theorem
Statement: Let u(x) and v(x) be nth
order differentiable functions
Q2. Define Tautology and contradiction. Show that
a) (pV q) V (~ p) is a tautology.
b) (p^ q) ^ (~
p) is a contradiction [2+2+3+3] 10 marks
Answer.
a) A statement is said to be a tautology
if it is true for all logical possibilities. In other words, a statement is
called
b)
c)
Q3. State Lagrange’s Theorem. Verify
Lagrange’s mean value theorem for the function f(x) = 3 x2 – 5x + 1
defined in interval [2, 5] [2+8] 10 marks
Answer.
Lagrange’s Theorem
Let f: [a,b] ->R be a
continuous function such that f: (a,b)->R is differentiable. Then, there
exists c ε (a,b) such that [f(b)-f(a)]/(b-a)
=f’(c).
Geometrical Interpretation
Q4. Define
Negation. Write the negation of each of the following conjunctions:
a) Paris is in
France and London is in England.
b) 2 + 3 = 5 and 8
< 10. [2+8] 10 marks
Answer.
Negation
An assertion that a statement
fails or denial of a statement is called the negation of the statement. The
negation of a statement is generally formed by introducing the word “not” at
some proper place in the statement or by
Q5. Find the asymptote parallel to the coordinate axis of the following
curves
(i) (𝑥2+𝑦2)x−𝑎𝑦2=0
(ii) 𝑥2𝑦2−𝑎2(𝑥2+𝑦2)=0 [5+5] 10
marks
Answer.
Solution: (i) We have (𝑥2+𝑦2)x−𝑎𝑦2=0
Or
x3+(x-a)y2=0
Asymptote

set [5*2] 10 marks
Answer.
(i)
Set
A set is a well defined collection of
objects. The following points may be noted:
i)
Objects,
