What is the value of (\tan 0^\circ)?

Answer and explanation

Correct answer: (0)

The correct answer is option B: \\(0\\). Tangent is defined as \\(\tan\theta=\frac{\sin\theta}{\cos\theta}\\). At zero degrees, \\(\sin0^\circ=0\\) and \\(\cos0^\circ=1\\). Hence \\(\tan0^\circ=0/1=0\\). Option A, 1, is not the tangent value; it is associated with some other standard trigonometric values. Option B is correct because the numerator is zero while the denominator is nonzero. Option C, \\(\sqrt3\\), is the tangent of a different standard angle, not 0 degrees. Option D, \\(1/\sqrt3\\), also belongs to another angle and is not applicable here. Do not confuse \\(\tan0^\circ\\) with \\(\tan45^\circ=1\\). Memory cue: at 0 degrees, sine is 0, cosine is 1, so tangent is 0.
