2^(x+1) = 2. 2^x , 4^x = (2^x)^2 plug in 2^x = tan y and see the magic! (simplification :P)

will it really works :PPPP lol i hate chain rule _

don't wanna use chain rule for inverse trig ...........

? what did you get after simplification ?

i don't think chain rule is required here...

use tan(x+y)=(tanx+tany)/(1tanxtany)

@Abhishek619 :/

hartnn Group TitleBest ResponseYou've already chosen the best response.1
same thing....tan 2 thetha comes from tan (x+y) formula only

@Abhishek619 oh :OO yeah we can do it in that way also :OOO tahnx :)

hartnn Group TitleBest ResponseYou've already chosen the best response.1
with substitution, you would have got the same thing...

let me first @hartnn use ur method :D

@Abhishek619 @hartnn answer is [2^(x+1)loge2]/(1+4^x) :'(

hartnn Group TitleBest ResponseYou've already chosen the best response.1
i am never interested in final answer, just the method..... if your algebra part is correct, you WILL get correct final answer....

kittycat01 Group TitleBest ResponseYou've already chosen the best response.1
but the answer is in loge2 and having (1+4^x) also

well did he wrote 2tan^12^x?????????

2tan^1(2^x)

hartnn Group TitleBest ResponseYou've already chosen the best response.1
ok, got till 2 tan inverse 2^x, right ? if you diff. that u get 2 * (1/1+(2^x)^2) 2^x ln 2 (ln = log_e) .... (2^x ln 2 comes from chain rule) yes...

then m getting the answer :)

hartnn Group TitleBest ResponseYou've already chosen the best response.1
yeah... (2^x)^2 = 4^x and 2.2^x = 2^(x+1) good!
