Web2tan −1(sinx)=tan −1(2secx)We know, 2tan −1x=tan −1(1−x 22x)So, 2tan −1(sinx)=tan −1(1−sin 2x2sinx)According to the question,tan −1(1−sin 2x2sinx)=tan −1(2secx)⇒ 1−sin 2x2sinx = cosx2⇒ cos 2xsinx = cosx1⇒ sinx=cosx⇒ cosxsinx=1⇒ tanx=1⇒ … WebJul 3, 2014 · tan^2 x +sec x=1. We know that tan=sin/cos and sec= 1/cos. sec x = 1/cos x and (tan x)^2 = (sinx/cosx)^2. From the fundamental formula of trigonometry, (sin x)^2 = 1- (cos x)^2. (sinx/cosx)^2 = (1- (cos x)^2)/ (cos x)^2. The expression will become: (1- (cos x)^2)/ (cos x)^2 + 1/cos x = 1. We'll do the math so that all terms of the both sides of ...
