What is the fundamental period of (\tan \theta)?

Answer and explanation

Correct answer: (\pi)

A period is the smallest positive angle by which a function repeats its values. For tangent, the identity \\(\tan(\theta+\pi)=\tan\theta\\) holds because both sine and cosine change sign when \\(\pi\\) is added, so their quotient remains unchanged. The tangent graph therefore repeats after every \\(\pi\\) radians.

The word “fundamental” means the smallest positive period. Although \\(2\pi\\) also returns the same value, it is not the fundamental period because it is twice as large as necessary. The value \\(\pi/2\\) is not a period; it shifts a tangent graph toward a point where the function is undefined. Hence option C, \\(\pi\\), is correct. Sine has fundamental period \\(2\pi\\), which should not be confused with tangent.
