Verify each trigonometric equation by substituting identities to match the right hand side of the equation to the left hand side of the equation.

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

the 3rd line from the end.

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

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

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

ganeshie8 Group TitleBest ResponseYou've already chosen the best response.8
still fine ?
 2 months 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 !
