QUESTION: 4

Solution:

QUESTION: 5

Solution:

cos x and sin x are finite whatever x may be

QUESTION: 6

Solution:

QUESTION: 7

Which of the following functions is not differentiable in the domain [-1,1]?

Solution:

QUESTION: 8

If f(x) =    then limx-►3 f(x) will be

Solution:

QUESTION: 9

Solution:

= 1/12

QUESTION: 10

What should be the value of λ such that the function defined below is continuous at x = π/2?

Solution:

By the given condition

From (1), λ = 1

QUESTION: 11

The value of the function

Solution:

QUESTION: 12

Consider the function f(x) = |x|3, where x is real. Then the function f(x) at x = 0 is

Solution:

QUESTION: 13

The expression e–ln x for x > 0 is equal to

Solution:

QUESTION: 14

Consider the following two statements about the function f(x) = |x|

P: f(x) is continuous for all real values of x

Q: f(x) is differentiable for all real values of x

Which of the f oll owi ng is TRU E?

Solution:

The graph of f(x) is

f(x) is continuous for all real values of x   Lim |x| = Lim |x| = 0

as can be seen from graph of |x|.

and  Lim f(x) = +1 as can be seen from graph of |x|

x → 0+

Left deriva tive ≠ Rig ht derivative

So |x| is continuous but not differentiable at x = 0.
