GATE | GATE-CS-2014-(Set-1) | Question 16
(A) I only
(B) II only
(C) Both I and II
(D) Neither I nor II
Answer: (C) Explanation: In the given question,
ranges from
to
.
When
=
, the value of the function is 0, since Rows 1 and 2 are the same.
When
=
, the value of the function is 0, since Rows 1 and 3 are the same.
Therefore,
The given function is continuous and differentiable in the given range since it is a trigonometric function.
Then According to the Mean Value Theorem,
There exists a value
of such that
. So the first statement is true.
Also there may also exist a value
, such that
. This is because the function is not a constant function, i.e. all values in the range are not equal to
.
So the second statement is also true.
Therefore the correct option is
C.
