Column IColumn II
(a) The tangents of two acute angles are 33 and 22. The sine of twice their difference is(p) 11
(b) If n=π4αn=\frac{\pi}{4\alpha}, then tan⁡αtan⁡2αtan⁡3α…tan⁡(2n−1)α\tan\alpha\tan2\alpha\tan3\alpha\dots\tan(2n-1)\alpha is equal to(q) 00
(c) If x=ycos⁡2π3=zcos⁡4π3x=y\cos\frac{2\pi}{3}=z\cos\frac{4\pi}{3}, then xy+yz+zx=xy+yz+zx=(r) 12\frac12
