Which of the following trigonometric functions is odd and has fundamental period \(2\pi\)?
Answer and explanation
Correct answer: \(\sin x\)
Since \(\sin(-x)=-\sin x\), \(\sin x\) is an odd function, and its fundamental period is \(2\pi\). Although \(\tan x\) is also odd, its fundamental period is \(\pi\). In exams, verify each condition separately.
