Nếu tanx=1, tính giá trị của tan(2x).

... tan ⁡ 2 ( x ) \small{\tan(2x) = \dfrac{2 \tan(x)}{1 - \tan^2(x)}} tan(2x)=1−tan2(x)2tan(x)​. tan(2x) = [2 tan(x)] / [1 -. Half-Angle Identities. sin ⁡ ( x 2 ) = ... Sep 1, 2011 ... i.e. tanx = 1. This means (in this interval) that x = π/4. So π/4 is the only critical number. This means we have to check the points 0, π/4 ... is convenient to expand ¢1 ( k) in a series with respect to € = ( t0/Tsp )( 1 + iTsp~w) ( € « 1, when t0 I ~w I « 1 ). We now have. _oo. V3e \ dx.
