Question:medium

If \(0 < \theta < \frac{\pi}{2}\) and \(\tan 30^\circ \neq 0\), then \(\tan \theta + \tan 2\theta + \tan 3\theta = 0\) if \(\tan \theta \cdot \tan 2\theta = k\), where \(k =\):

Show Hint

When solving trigonometric equations involving sums of tangents, try using the standard identities for tan(2θ) and tan(3θ) to express them in terms of tan θ and simplify.
