Best ResponseYou've already chosen the best response.8ok thnks :) pick the side that has more terms, and do SOMETHING and try getting to the other side

Best ResponseYou've already chosen the best response.8here, the right side has more terms, right ?

Best ResponseYou've already chosen the best response.8ya so we start with that side, and work, and prove that it equals left side.

Best ResponseYou've already chosen the best response.8\(\cot x + 2\tan x + \tan^3 x\) \(\frac{1}{\tan x} + 2\tan x + \tan^3 x\) \(\frac{1+ 2\tan^2 x + \tan^4 x}{\tan x}\) \(\frac{1+ \tan^2 x + \tan^2x + \tan^4 x}{\tan x}\) \(\frac{\sec^2 x + \tan^2x + \tan^4 x}{\tan x}\) \(\frac{\sec^2 x + \tan^2x(1 + \tan^2 x)}{\tan x}\) \(\frac{\sec^2 x + \tan^2x(\sec^2 x)}{\tan x}\) \(\frac{\sec^2 x(1 + \tan^2x)}{\tan x}\) \(\frac{\sec^2 x(\sec^2 x)}{\tan x}\) \(\frac{\sec^4 x}{\tan x}\) \(\cot x\sec^4 x\) = LEFT HAND SIDE

Best ResponseYou've already chosen the best response.8you're fine, till this line ?

Best ResponseYou've already chosen the best response.8good, next factor out `sec^2x` from both terms, you get : \[\large \frac{\sec^2 x(1 + \tan^2x)}{\tan x}\]
