If f (x) = sin (
x)(where [ . ] denotes the greatest integer function) has π as its fundamental period, then -
x)(where [ . ] denotes the greatest integer function) has π as its fundamental period, then -Options
A.a = 1
B.a = 9
C.a ∈ [1, 2)
D.a ∈ [4, 5)
Solution
f(x) = sin (x)
Period =
= π
[a] = 4 ⇒ a ∈ [4, 5)
x)Period =
= π[a] = 4 ⇒ a ∈ [4, 5)
