Sep 26, 2014 ... tanx can take any value in (−∞,∞). So you find the range for 3−x1−3x for x∈[0,+∞). Jan 28, 2021 ... NTA Abhyas 2020: If the area bounded by f(x)=(tan)3 x+tan â ¡ x from x=0 to x=(π /4) is k square units, then the maximum value of g(x)=ksin ... The first part is relatively simple. If we write tan(3x) as tan(2x+x) we can use addition formulae to give: tan(2x+x)= (tan(2x)+tan(x))/(1-tan(2x)tan(x)) Given: [(sec3x - tan3x)/(sec x - tan x)] - 2 tan2x - sec x tan x Formula used: ⇒ a3 - b3 = (a - b)(a2 + ab + b2) ⇒ sec2 x - tan2x&.
