Tan(AB) = tanAtanB/1tanAtanB From this formula we can derive tan(2x) as tan(xx) So tan(2x)= 2tanx/1tanxtanx We can always go for the longer approch from sinx/cosx to derive this formulaSince both terms are perfect squares, factor using the difference of squares formula, a 2 − b 2 = ( a b) ( a − b) a 2 b 2 = ( a b) ( a b) where a = 1 a = 1 and b = tan 2 ( x) b = tan 2 ( x) ( 1 tan 2 ( x)) ( 1 − tan 2 ( x)) 1 − tan 2 ( x) ( 1 tan 2 ( x)) ( 1 tan 2 ( x)) 1 tan 2 ( x) Simplify Misc 44The value of ∫_0^1 tan^(−1)⁡((2𝑥 − 1)/(1 𝑥 − 𝑥^2 )) 𝑑𝑥 is equal to (A) 1 (B) 0 −1 (D) 𝜋/4Let I=∫_0^1 tan^(−1)⁡((2𝑥 Misc 44 Mcq Value Fo Tan 1 2x 1 1 X X2 Dx Is 1-tan^2x/1+tan^2x formula
