its like above ?

its tan cubed x at the end other then that yes

ok thnks :) pick the side that has more terms, and do SOMETHING and try getting to the other side

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.8
here, the right side has more terms, right ?

logynklode Group TitleBest ResponseYou've already chosen the best response.0
what? the irght side has more terms yeah

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.8
ya so we start with that side, and work, and prove that it equals left side.

\(\cot x + 2\tan x + \tan^3 x\) \(\frac{1}{\tan x} + 2\tan x + \tan^3 x\) \(\frac{1+ 2\tan^2 x + \tan^4 x}{\tan x}\) \(\frac{1+ \tan^2 x + \tan^2x + \tan^4 x}{\tan x}\) \(\frac{\sec^2 x + \tan^2x + \tan^4 x}{\tan x}\) \(\frac{\sec^2 x + \tan^2x(1 + \tan^2 x)}{\tan x}\) \(\frac{\sec^2 x + \tan^2x(\sec^2 x)}{\tan x}\) \(\frac{\sec^2 x(1 + \tan^2x)}{\tan x}\) \(\frac{\sec^2 x(\sec^2 x)}{\tan x}\) \(\frac{\sec^4 x}{\tan x}\) \(\cot x\sec^4 x\) = LEFT HAND SIDE

@ganeshie8 i dont understand ur solution

hmm which line ?

mayaal Group TitleBest ResponseYou've already chosen the best response.1
the 3rd line from the end.

\[\large \frac{\sec^2 x + \tan^2x(\sec^2 x)}{\tan x}\]
 one month ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.8
you're fine, till this line ?
 one month ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.8
good, next factor out `sec^2x` from both terms, you get : \[\large \frac{\sec^2 x(1 + \tan^2x)}{\tan x}\]
 one month ago

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.8
still fine ?
 one month ago

mayaal Group TitleBest ResponseYou've already chosen the best response.1
oh,ok.so u factored out the sec^2x from the whole numerator?

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.8
exactly !
