Webb27 sep. 2024 · If t is a rational number, then t = p q for some positive integers p, q such that gcd (p, q) = 1. By the rational root theorem, p, q ∣ 180, so we can write t = n 180 for some integer n. Because π 180 < tan π 180 < tan(π / 4) 45 = 1 45, where the first inequality is due to the inequality tanx > x for all x ∈ (0, π / 2), and the second ... WebbShow that $2\tan^{-1}(2) = \pi - \cos^{-1}(\frac{3}{5})$ So, taking $\tan$ of both sides I get: LHS $=\frac{2\tan(\tan^{-1}(2))}{1 - \tan^2(\tan^{-1}(2))} = -\frac{4 ...
