1.	Find the domain of f(x) =1/1-2cosx
Answer» Step-by-step explanation: GIVEN, a function - F ( X ) = 1 1 − 2 cos x We need to FIND the domain of the given function. Since the denominator can not be zero, then - 1 − 2 cos x = 0 should be REMOVED from the domain of the function. Hence, cos x = 1 2 ⇒ x = 2 n π ± π 3 Hence, the domain of the function - x ∈ R − ( 2 n π ± π 3 ) Where n ∈
