If tanx= -1/3, cos>0, then how do you find tan2x? Socratic
Web10 jan. 2024 · Since tan blows up at ± π 2, there is a simple argument. Suppose tan is uniformly continuous on ( − π 2, π 2). Then there exists δ > 0 such that x − y < δ implies tanx − tany < 1. Let N be any integer larger than π 2δ. Let x0 ∈ (0, π 2) be such that tanx0 > 2N. Define xk = N − k N x0 for k = 1, …, N.
