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)) 1. x + 2x = 3x 2. \tan(A + B) = \dfrac{\tan(A) + \tan(B)}{1 - \tan(A)\tan(B)} 3. \displaystyle \int Aug 18, 2020 ... Let I = Consider tan 3x = tan (2x + x) = ∴ tan3x (1 – tan 2x tan x) = tan 2x + tan x ∴ tan 3x – tan 3x tan 2x tan x = Thus, we have shown that tan3xtanx never lies between 13 and 3. Show More. |.
